3.5 stars! I flew in and out of this airport a couple of times and it's a pretty decent international airport.
CONCESSIONS: There are plenty of shops to pick up some last minute souvenirs, like the Britt shop, where you can buy mugs, shirts, bottles of pisco, mini Rapa Nui moai figurines, and Cafe Britt coffee and chocolates and alfajores. There are some mini markets to pick up premade sammies, drinks, magazines, etc. There's also a Cruz Verde pharmacy in case you need to pick up some supplies. Food-wise, there were a few restaurants in pre-security/landside, as well as a Dunkin Donuts and a Telepizza. In the domestic terminal, post-security, there was a Victoria's Secret, Bath & Body Works, a Starbucks, and a couple other eateries and stores. In the international terminal post-security, there were duty-free stores, Starbucks, Subway, etc.
WIFI: There is now free wifi at the airport - you have to register with email or some social media account. It's pretty good wifi, although sometimes it kicks you off and you have to re-login.
PUBLIC TRANSIT: There are two buses that I know of that will connect you with the metro system of Santiago. Centropuerto is one and it will take you all the way to Los Heroes metro, and there you can transfer onto a local bus or the metro to get you to downtown Santiago. TurBus is a major bus company that runs the other bus and will take you all the way to Terminal Alameda bus station, which is where the University of Santiago metro stop is. Both options are pretty cheap (1600 pesos for Centropuerto, 1700 pesos for TurBus), just make sure you have cash to pay. The buses run pretty frequently during the day and night (not sure about late at night or too learly in the morning). Super convenient and inexpensive way to get into town. I prefer taking TurBus.
OTHER: Plenty of ATMS (called cajero automatico) to withdraw some pesos. Charging stations by gates to charge your phone. Each time I came to the airport to depart, lines were pretty long, so if you have to check in a bag, come EARLY. Checking in with Sky Airlines took the longest - we were nearly in line for 50 minutes just waiting to drop off our bags! Luckily, staff came around asking if people were on a certain flight that was about to leave, so that they could be moved ahead, but it took a ridiculously long time. The lines for LAN and United weren't nearly as long, but it wasn't quick. Come early!
Overall a solid international airport! Buen viaje!
