Which U.S. airline offers the best domestic first class experience

Delta Air Lines' Delta First is noted for its standout base product among major US airlines. Its narrowbody fleet includes seatback in-flight entertainment (IFE) screens and free Wi-Fi access on most aircraft. Food service varies by flight length, with meals offered on longer routes.

United Airlines phased out long-haul first class nearly a decade ago in favor of United Polaris business cabins. Domestically, United First spans its network and some short regional international flights. Although not all cabins feature IFE screens, the airline is installing them fleet-wide.

While each carrier's domestic first-class offerings vary slightly, common perks include expedited airport services and priority boarding. Seat quality improves over economy with enhanced pitch and width. Meal services are generally available except on shorter routes.

Despite these amenities, none of the three airlines provide lounge access for domestic first passengers unless traveling certain premium routes or holding specific memberships or statuses.

Excluding Flagship First from consideration, Delta appears to lead due to complimentary WiFi and extensive IFE screen availability. Reviewers often commend Delta for service quality and reliability. Operationally, Delta was recognized as the most punctual US airline in 2024.

"Delta would probably come out on top with its complimentary WiFi," reflecting broader sentiment among flight reviewers who praise "Delta First...for its quality of service."

The Wall Street Journal highlighted Delta's consistent ranking as the best US airline over recent years.
