Ontario International Airport

Ontario International Airport is a pretty well-managed small airport. I’ve never been through security this fast—less than 5 minutes, which is the quickest in my entire travel experience. The airport has limited gates but everything is organized and well managed, making it an easy and stress-free option compared to larger airports.

5 star airport experience. Special thanks to the shuttle driver. I had a fantastic experience at the airport. Everything was fast, convenient, and the entire place was impressively well maintained. But what really stood out was the exceptional service from the lady driving the shuttle bus. She went above and beyond for every single passenger. Not only was she helping people with their luggage and making sure everything was stored properly, but she also greeted everyone with a warm, welcoming attitude. She made it a point to look around and ensure no one got left behind, showing genuine care for each person boarding. Her attentiveness, professionalism, and kindness made what is usually a routine part of travel feel incredibly pleasant. People like her make a real difference. She deserves recognition for the pride she takes in her job and the way she treats travelers. Thank you for making the experience so smooth and memorable!

We flew out of and flew back into the Ontario Airport. This airport seemed well organized and the staff were nice. Lots of food places to grab a bite or drink. We checked our bags in with no issues. Air Conditioning was running and the bathrooms were clean. TSA PreCheck went smoothly.

Layout is good. Not so far to the baggage claim, but a little bit difficult to pick the baggage. It's seems one way of conveyor and don't know how many time will see the baggage again.

First time using this airport! The landing was smooth! It’s a nice and small airport!! I like the coziness environment! Keep up the good service! Cheers 🥂

Flown out of ONT numerous times, and every single experience has been smooth and stress free. The airport is easy to get in and out of, security lines usually move quickly or you're the only one there getting checked. Compared to LAX, it feels far less crowded and there's no traffic usually. This airport has become my go to place to fly out. Fast, efficient, and stress free.

ONT Airport is overall a good airport. I went there for a flight to SEA TAC, and it was a good experience. The lines were short, the staff was nice, and overall, I would recommend this airport more then LAX. However, I think SBD is the best.

Ontario is great! Far better than LAX. Less traffic, fast lines, and the terminal setup is better to get in and out quickly. I only wish they had more flights! This year they're flying into BJX Mexico on Volaris, so no need to drive all the way to CBX bridge in San Diego anymore.

Disclaimer: This review is specific to ONT's Valet Parking. Airport itself is 4/5 stars with valet being the sole reason keeping it from 5/5. Valet parking is terrible 2/5 stars. Ive used it three times hoping it'll get better and was just a rare occurrence. None of the experiences was worth $40/day. Biggest complaints: 1) They advertise 10% off for booking online. This is false. Fine print says only a limited number of discounted parking spots. Have never received a discount, and have never known anyone to. Seems like false advertising. 2) My first time using valet, I arrived and no one was there even though I booked a reservation a couple days in advance. I was traveling with car seats and strollers and multiple checked bags so it wasn't as simple as just parking in one of the lots (plus I'm 100% certain they would've charged a no-show or cancellation fee). Nearly missed my flight waiting for someone to arrive to hand my keys to. You'd think they would have a drop box. 3) One of the times I returned, my flight was delayed due to storms. Arrived 3-4hrs late and I was charged for a FULL day. $40 for 4 extra hours. Was not prorated at all. SNA has a grace period at least, worst case I have been charged the hourly rate, but full day is ridiculous. 4) I assumed valet had an offsite garage - wrong. Your car is just kept at the back of the standard lots, meaning every time I got my car back it was absolutely filthy. Caked on dirt just from being inland. For anyone that takes pride in their cars appearance and keeps it garaged, this is a warning for you. The one benefit is that your car is waiting for you curbside when you return, but this is the definition of valet and the absolute minimum expectation - so not sure if it's a true "benefit". ONT, please do better. When SNA is equal-distant, this is a make or break when choosing between similar airline fares.

Ontario International airport is located in Ontario California. It's a smaller airport but very convenient. The entrance , where you drop off n check in your luggage is nearby therefore super convenient. I love that you can fly out of Ontario and end up so far away and then come right back to this convenient airport . If you are in the IE or in SoCal give this airport a try .

This was my first time going to this airport. I live about an hour away and had to pick up my daughter's best friend. I was really hoping it would be better than going to SD or LA, I hate doing that. The route to the airport was super easy taking the 15North to the 60 west. We had no problems making it to the terminal we needed. There are lots of signs directing you and we found Alaska quite quickly. Parking was a breeze, grabbed the ticket from the machine, parked and walked across the street into the building. Upon entering we asked if we could go up to where the passengers depart the planes. In my recollection at SD airport you have to drop off people or walk them in but can't go beyond a certain point. So when the guard told me I could scan a QR code and fill in the form and submit it on my phone I could then go up the escalator to await our friend. We got upstairs, removed our shoes and placed our items in the bucket to go through the X-ray machine. The security checked our IDs and that was it, barely took 10 min to get through. That could be because I now have a Real ID, not sure. There are your usual restaurants, and stores selling magazines, drinks , snacks etc. There was even a Dunkin Donuts, in another part of the airport there is an Einstein's. We watched the planes come in and our friend arrived safe and sound. All in all it was a very easy and stress free experience. Upon leaving the parking lot you have a few options of ways to pay. I went through the one where you pay by card. The cost for less than an hour was $12, kinda pricey but worth it to not deal with so many cars, traffic and chaos. I will definitely be flying out of here on my next trip!

Ontario International Airport is kind of a well-known airport in the city of Ontario. For that reason, it is why we love flying in and out of it. I have been here so many times to go to Las Vegas and even to Asia! It can go almost anywhere you just have to check for flights flying in and out of here. There is a variety of different airlines such as Frontier, United, Jet Blue, South West, and China Airlines.

It's a nice and small airport that you can access easily but it's not reliable cuz our flight got delayed by 2 hrs and later I got additional 15 mins delayed... seems like delaying happening quite often for whatever reasons. But I like the small and coziness, wishing they'll be more reliable. Work it out! Cheers

Fast becoming one of my favorite airports! It's small with 2 terminals and you can get from curb to gate in 15 minutes with TSA PreCheck! My most recent flights were to and from Seattle out of Ontario Airport. I got smart this time and scheduled my flights so there wasn't traffic and it worked perfectly for my trip! This is so much better than LAX and SEA. The only bad thing is the limited food options, but make sure to bring snacks and be prepared. I love the baggage claim carousel! The edges are flush so it's easy to pick up large bags. However, I'm thinking the down side would be some bags may fall down near the corners. Uber is convenient to for pick up and drop off at the curb. You don't have to walk to another terminal or take a train to the Rideshare area. Definitely recommended!

Ontario is one of my favorite airports.... It's still small enough to get in and out without a lot of fuss.....it's so much better than LA... my kids dropped me off... so that's a plus... parking is a not fun.... traffic getting here was a mess....

We flew out of and flew back into the Ontario Airport. The airport seems well organized and the staff were nice. Lots of food places to grab a bite or drink. We checked in our bags with no issues. Air conditioner was running and the bathrooms were clean.

I would choose ONT over LAX any day. I've been flying out of this airport for years and have never had an issue. Since it's much smaller, checking in and getting through security is usually fairly quick. There is less traffic for the most part unless you are traveling during a major holiday of course. Although flights can be a little more expensive, I don't mind since the environment is a lot less stressful than other airports.

Everything went by soooooo smooth I was in and out of TSA within 10 min . That's a record!!!

Such a a calm collected easy accessible airport with a Ramen machine that's provided. This is an airport I will definitely fly back into when I come this direction again.

This is a one of my favorite airports. Everything goes by very smoothly and quickly. I would go to this airport 100% before LAX.

4++ i'm not sure if I was lucky or I came on the right night, but this is one of the easiest airports to use logistics wise. I pre-bought my parking and walked over which wasn't too far. I got through security really quickly (helps I have TSA pre-check) Overall, just one of the least painful experiences I've had at any airport ever. As long as the prices are reasonable for the flights, has the route I'm looking for, and if I can get out here, this is probably my preferable location to fly out of in Southern California.

Always will fly out of here and not LAX. Has a great lounge if you have Amex or Priority Pass. Has Clear so super easy through TSA!

Way less busier than LAX, Ontario airport is a great alternative to travel out from. Adequate parking and there are free shuttles to drop you off to your airline terminal. Surrounding area is easier to navigate through as well since the airport is located in a suburb. If you can get a flight through here, book it. Your sanity will thank you for it.

My first time at Ontario airport and I'm very satisfied. It was so easy to check in and if I get TSA pre-check it's even easier it was so fast. Is very small they have very good food options to choose from and everything works fast smooth operation. I got Dunkin' Donuts, but they did have other eateries and they did have Chick-fil-A . Was early in the morning flight and I highly recommend if you want less hassle . I would come back here for sure! -Marshay D.

If you can travel through Ontario vs lax I highly recommend it. Getting in and out is hassle free! I wish I could always fly from here!

Say it isn't so!! I could swear I wrote a review for this airport already, but apparently not! **GASP** Ontario International Airport (ONT) is one of my top 3 airports! It is a quick in and out kinda airport, and I love how fast I can check in, board and be in the air and on my way. They have some good dining options, and on my last flight out of here, I found the Farmers Fridge vending machine which I saw on IG! It was past my gate, but I had ample time, and came early specifically to try this, lol. Was it worth it? YES! Healthy and reasonably priced at an airport?! Sign me up!! Chick-fil-A is just down at the other end, and I married the 2 for a healthy grilled cobb salad. They also have a Dunkin Donuts at the top of the TSA check point, before you start your walk to the 400 gates. I don't think I've ever seen it open, or maybe I just come at odd times. The restrooms here are pretty clean, too. TSA is usually quick and they don't normally have horrendous lines like the bigger major airports. I am a huge fan of ONT, and will continue to fly in and out of here on the regular! Avoid the hassle of LAX if you can, and fly ONT instead! ;)

#15 for 2024 Out of the LA area this is my preferred airport to fly into. Easy in, Easy out. Depending how long I will be away will determine if I drive in or take a LYFT. If you decide to leave your car there you will need to book your spot online. Go to https://www.flyontario.com/parking/lots to take care of that. There are 6 lots. Hourly and daily rates are available. Look at the map to decide which parking lots are close to your terminal. if you do park far there is a bus that goes around in a loop that can pick you up and take you where you need to go in the airport area. There is no fee to ride. They will also lower the bus to make it easier for you to bring your big, heavy bulky luggage. If you rent a car the bus can take you there too. There are gas stations close by you can refill before you return. They don't have the best price but they do tend to be cheaper than in the LA city itself. Thankful for that. If you do take LYFT it is best to schedule a pick up on your return to avoid waiting hours in the later evening when there are not many drivers available or none that want to travel far. Best to schedule that 24hrs in advance. From check in to TSA it's a short walk. After that walking to the gates will vary depending on your designated gate. Not all the time, fares from here do tend to be cheaper than most other airports in the area especially LAX. When it is cheaper to use LAX I find the difference in fare is not enough to go to LAX. That includes flying international as well. There's no traffic getting in and no traffic getting out. So why wouldn't you come to the Ontario International Airport?

Omg. ONT. I've heard all the commercials. "Better", "easier", "cleaner", "faster".....BOOOOOOO!! It isn't!! It's NONE of the above.... Don't waste your time unless this is your home airport!!! It's like LAX. Which is NOT a compliment. TSA line has been 45 minutes upon getting up the escalators... then another 25 minutes through TSA gate...both times I've travelled through ONT. Inside the terminal after TSA.... Very little air conditioning.... Yikes.. I mean, YIKES.... Aspire Lounge. AMEX/Priority Pass free, otherwise it's $55. I paid because it's better than buying $55 worth of junk at the stores IMO :). But it's very "meh". And very small too... seats probably 45-50 at max capacity... which is what happened when I went. I wouldn't say I'd fly via LAX.. because they are the worst, but ONT is second on my list.

My rating is 3 stars because customer service is huge to me. My flight arrived at 11pm. We were the last to get off of the plane. By the time we got our luggage, found the shuttle to get to the rental car all rental companies are closed. Not the total fault of the airport but surely they could communicate better with their partners. You know you have flights that come in that late so people are consistently stuck. It reflects poorly on the airport because it causes customers like myself not to want to use this airport if I need a rental.

This airport is all about convenience! I've flown out of this airport for almost 20 years and its nice to not deal with larget airports if you don't have to. Convenient parking and the rates aren't ridiculous.

The Ontario airport was a nice little airport. I'd actually never flown out of it before and was pleasantly surprised to see that the day before they had one of the greatest track and field runners, Jackie Joyner-Kersee there to sign books and autographs-- wish ai was there for that! But overall the airport was pretty straightforward, it's not a long walk at all from the front to security and TSA had no one waiting so Precheck was a breeze. We flew out of Southwest and our gate had a Chick-fila that wasn't terribly busy, but had a steady stream of customers at 7am. There was also another full sit down restaurant across the way from chick-fila. I ventured to some restrooms that were kind of far, but sooo clean. They smelled like vanilla when I walked in! Overall, I'd recommend this airport!

Everything about the place was good. Was very fast and efficient. If u live in inland empire and don't wanna get stuck in the LA traffic this is the best airport with good flight options as well

We were there to pick up a niece and nephew at almost midnight. We parked at the cellphone parking lot to await their arrival. The lot was fine, and at that time of night there was no one to enforce the 20 minute limit. Once their flight arrived we had to park behind a long queue of cars that were all parked illegally because there was insufficient room for drivers to pick up their arriving passengers at the front. A police unit forced all the drivers to move away from the red curb. We were fortunate that just then our niece and nephew made it to the front and we found an available spot to pick them up. Mind you this was after midnight on a Sunday/Monday. I don't know what it's like during the day, and I never want to find out.

I actually really like this airport compared to LAX airport. If you like less traffic and just overall a smaller airport, this is your place. We got direct flight on delta from Atlanta to this airport. Getting out of airplane to the baggage claim took five minutes. It was very fast. The service was fast and efficient. You don't have to walk very far and then you get your bags. The bathrooms could use some renovations and cleaning but they are decent. Like other reviewers said not many food options in the airport but still it's ok and the food establishments do close pretty early. The car rental and parking lots for your car, you need to take an airport shuttle which can get pretty crowded. It takes about 15-20 minutes to do this. But I rather fly into this airport than the crazy LAX airport which takes much longer most of the time.

Another great experience flying in and out of this airport. So fast and convenient. Security was a breeze to pass through and getting picked up by an Uber was so easy. They do have a dedicated ride share pick up area just past terminal 4, but really no need to walk all the way down there. Just wait wherever you exit the airport and you will get picked up by your driver.

I will always fly out of Ontario rather than LAX any chance I get. There is no comparison. It's never super crowded and going through TSA is quick. Uber pickup is just outside of Baggage Claim and is easy. It's always a good experience when flying out of this airport!

Busy, busy, busy, on a summer Saturday morning! People all over the airport, but I have to admit, TSA really got us through - my son in a wheelchair and all! Had an early lunch at the Chick-fila-A and was impressed! Southwest agents were a bit stressed with all of the customers, but all in all it was easy and simple, clean, and an easy process.

Great airport! 100000 times better than LAX, not a ton of traffic and have only 2 terminals and 2 lanes but everything is efficient. They also have a lounge for Priority Pass members. If there's a chance to fly in here instead of LAX I would do it!

It's a great airport If you like stop over flights and you don't mind paying an average of ten to fifteen percent more. It's called Ontario international airport though I'm curious how many direct flights they have to other countries. It seems they never have direct flights to where I ever want to go ( Memphis, Boston, Philadelphia, Europe etc.) and when I do find cities that they fly to they are more expensive with less frequent schedules. So yeah it's a great location for me but useless for the half dozen or so flights I take annually.

Quick drop off, quick check in, quick walk to the gate- this airport is spey convenient. I live in Rancho and love the fact that there's an airport less than 15 minutes from my house. I've used this airport for short trips to Las Vegas and even longer ones to NYC and I can't say enough good things about this place. Drop off and pick up might be a little backed up but it moves quickly. Yes it might be a little more expensive but it's worth the convenience. I'll definitely be using this airport again for my future travels.

This turned out to be much better than expected for a smaller airport in the region. Modern, clean, well maintained, and had good A/C throughout the aisles. Peaceful and relaxing. The airport design reminds me of the long building architecture view of the San Jose Mineta International Airport. It had a few good restaurants and Dunkin Donuts is in there. Restrooms are at a good walking distance, especially if you're flying out or departing Southwest Airlines. It was simple to walk through with easy access to the rental car facility down the main street/only few long blocks away. There's a convenient shuttle bus/no cost to drop you off at the front door of rental car building. Shuttle loops back to the terminals, so you won't get lost here. Weather and landscape was gorgeous. Parking lot was very organized and visible with labels of airlines. They actually have a huge lot throughout the airport area. Stress-free travel experience. It felt quiet and relaxed for most of the time. I would definitely fly here again instead of LAX which is always overly crowded and busy most of the time. This destination is perfect, especially if you are planning to drive west/Upland/Pomona/Chino Hills/Diamond Bar/Rowland Heights. Not far. There's a Costco gas station nearby too. People are more friendly here. Going through the gates was a breeze.

Always such a breeze to get through. They have truly streamlined the process for frequent flyers. TSA pre-check typically takes less than 8 minutes from the time you walk in the door until you're at your gate. They have increased their food offerings, tailoring it to a fast bite and to-go options. The new lounge has many options and a great spot to hangout and get some work done before a flight. Staff is always kind and helpful. The constant rotation of staff cleaning keeps this airport pretty neat.

Was my go-to airport because it's small and convenient, but they just doubled the parking fees, so I guess it's back to San Diego.

Great little airport to fly into the LA area, headed towards Big Bear so this location helped us be on our way in the right direction, closer, and less traffic and people to deal with which was nice. Easy to navigate, car rental was convenient and mostly friendly. We would fly in/out of this airport again.

My family and I take flights in this airport to avoid the LAX traffic jam. The only problem is during the night when the entire airport looks like it's abandoned except with every single light on. There is no security and no staff walking around. It feels like a prime crime spot. The last few times I flew at night, I was the only passenger at the airport until roughly 10 minutes before boarding. It's like a scene straight out of a horror movie. Overall, it feels like trading safety for convenience. I'm cheap though, so that won't stop me from coming back to this nightmare of an airport for my flights.

Something about Christmas decorations spruces up any interior. Ontario Airport today is abuzz at 4:44 a.m. with people traveling all over. How wonderful. May everyone have safe travels. Thank you TSA for doing your best to keep us safe as well.

If you are flying into the L.A. area, this works great. It may cost a little more but I prefer the ease and less crowds. Arrival was easy. Picking up luggage was fast.

I can only speak knowledgeably of Terminal 4 because I have not been through the others. Ontario is a nice sized airport, big enough to have places to eat and shop while you wait for your flight, but not so huge as to be a chore to check in and get through security. I arrived about 90 minutes prior to my flight. But since I had no bags to check, and already had my boarding pass, I only needed to get through security. It took very little time, especially since I had precheck. When you have precheck, they say you don't have to take off your belt, but the scanner beeped, and I had to take it off anyway, not a big deal, but next time I'll take if off anyway before I get to the metal detector. When you go through security, all they need is your ID and have you look into a camera. Face recognition technology tells them you are who you say you are. That's a bit scary if you've ever watched the TV show, "Person of Interest." It is what it is. Once in, I was able to get some coffee at Dunkin Donuts (they also have Starbucks and a few other eateries). Note for next time, Dunkin only takes cards, no cash. I prefer to use cash for small purchases, but "sigh" The seating area at the gate for my flight became quite full as the boarding time approached. Quite a few of us had to find a seat farther away at a gate nearby. Still, the airport had a nice feel, and lightyears better than LAX. When I go back to SoCal, I'll definitely keep Ontario Airport in mind as my preferred airport in the region.

Best airport in So cal! There are a couple lots where you can park your car. The closest one is $30 a day. The further ones are cheaper if you want to save. There's a walk but it's not that bad for as long as you have the time.

This airport does the job! It's close, not huge, but has plenty of flights leaving all the time. The check in area moves quickly and getting upstairs through security is not bad. There's usually a good amount of parking available as well.

Traveling between Hawaii and Southern California... This was the first time I've used the Ontario International Airport (ONT). I didn't even know where Ontario, California was. I just had to book this flight on Hawaiian Airlines because the flight to Long Beach Airport was full. The Rental Car Facility is about 0.6 miles away from the Ontario International Airport. There's a free shuttle that goes between Terminal 2, Terminal 4, Parking Lot 6, and the Rental Car Facility. The good thing about this Rental Car Facility is that it doesn't close as early as the Rental Car Center at Long Beach Airport. Costco Gasoline in Rancho Cucamonga is about 2 miles from the Rental Car Center. It opens at 5:30am on weekdays and 6am on weekends. Overall, this airport is clean, modern, and has less traffic than LAX, Long Beach, and Tom Bradley International Airport. I think I will be switching to ONT when I go to Los Angeles from now on.

New and clean is the first impression for me. I need to dropped off my family for their flight with China Airlines. Parking lot was across the terminal. Very convenient. Maybe because we were there in the evening tim

Flew into Ontario airport from Las Vegas and this airport is super easy to get around. By the time we got off our flight to go to baggage claim, the process was super efficient and fast. The only drawback about this airport is you have to take a shuttle to the rental car parking lot. We waited about 15 minutes for the bus to come around. And then it was about a five minute drive to the rental car lot to retrieve our rental. All in all this airport is super easy to get around and very efficient with our bags.

I love this airport because the signs are huge and it's great for my lack of eyesight and lack of attention span. Very organized and easy to get around. I also love the airport because it's very clean and it looks modern. There are just enough food places if you are hungry and there's a little aquarium and the Ontario sign is really pretty. it's very easy because it's small and manageable and the parking lot is really close and it's only 61 miles from Los Angeles. Bathrooms were clean.

Wayyyy better than LAX! Less traffic getting there and driving in and out of the terminal area is a breeze! Love dropping and picking up from this airport!

I really love how easily people can navigate throw this airport. It's one long building so there aren't too many corners or you can get lost behind. This airport also has a chick-fil-a so that is a huge plus in my book! lol Heavily a Southwest airport which I love! The airport itself is pretty accessible from the freeway with a bunch of parking. There are many app friendly pick up drivers who are constantly there so the wait isn't long to be picked up.

This is my favorite go to airport. I always look for flights out of here before I look for flights out of LAX. If I'm flying with Alaska Airlines or JetBlue Airways, that would be out of terminal 2. If I'm flying with Southwest Airlines, American Airlines, or Hawaiian Airlines, that would be out of terminal 4. Terminal 4 is the closest to the 2 economy parking lots, 5 and 6. Currently, it costs $18 per day to park there.
