7 Business-Class Seats That Are Actually Worth the Price | Condé Nast Traveler

"When I flew in Delta One Suites the private enclosed suites on select aircraft felt like a major step up from older business-class cabins: memory-foam cushion seats that convert to lie-flat beds, a closing door for privacy, mattress pads that wrap over the seat, lumbar pillows, larger duvets, slippers, and Missoni amenity kits with toiletries from The Grown Alchemist, plus Delta One lounge access at JFK and LAX and restaurant-quality meals often developed with well-known local chefs; these suites are most commonly found on Delta's Airbus A350s and A330-900neos (older 767s do not carry them)." - Ramsey Qubein
