Before this announcement, travelers flying nonstop between New York and Orange County had one realistic premium option American Airlines. United Airlines operates between Newark and Orange County, but uses a Boeing 737-700 with a standard domestic product, not a lie-flat cabin.
Delta's entry gives the JFK–SNA corridor two competitive lie-flat business-class products for the first time. Here is how the two airlines compare on the things that matter most to premium travelers
Lie-flat seating: Both Delta One and American's Flagship Business offer full lie-flat beds on this route. American's Collins Diamond seats and Delta's Delta One seats are broadly comparable in comfort.
First Class: American's A321T includes a Flagship First cabin above business class. Delta's 757 does not have a first-class section Delta One is the top cabin.
Lounge at JFK: Delta One passengers get access to the Delta One Lounge, which is widely considered superior to American's Greenwich Lounge at JFK for the business-class experience.
Lounge at SNA: American has an Admirals Club at John Wayne Airport. Delta does not have a lounge at SNA, which is an advantage for American on the Orange County end.
Economy cabin: Both airlines offer a standard economy experience, though American has historically provided complimentary meals in coach on its transcontinental A321T flights, a benefit Delta does not match in Main Cabin.
