The State of Domestic First Class in 2025

In June 2025, United Airlines and American Airlines are both rolling out new premium cabin experiences. United’s “Elevated” interior, featuring Polaris Studio seats, is appearing on more routes, while American is keeping its exclusive Flagship First on select transcontinental flights. Delta, meanwhile, continues to lead in customer satisfaction, focusing on consistent service and ongoing upgrades to its First Class product and Sky Club lounges.

All three airlines are competing to attract premium travelers, especially on routes between major cities like New York and Los Angeles or San Francisco. While no major policy changes have been announced in the past week, the race to offer the best domestic First Class experience is more intense than ever.

What Sets Each Airline Apart?

American Airlines: Flagship First and Beyond

American Airlines stands out for its Flagship First product, available only on the Airbus A321T aircraft flying between New York (JFK) and Los Angeles (LAX) or San Francisco (SFO). This is the only true lie-flat First Class seat offered on domestic routes in the United States 🇺🇸. Passengers in Flagship First enjoy:

• Lie-flat seats for maximum comfort on long flights
• Exclusive lounge access at the Chelsea Lounge in JFK
• Chef-curated meals and premium drinks
• Priority boarding and check-in
• Enhanced entertainment options

On other aircraft, American’s First Class offers recliner seats, priority boarding, and complimentary meals and drinks. However, the experience can be less consistent compared to Flagship First. According to analysis by VisaVerge.com, American’s AAdvantage program remains unchanged for 2025, with new tiers for Million Miler status and extended validity for systemwide upgrades.

Delta: Consistency and Customer Service

Delta is known for providing the most consistent First Class experience across its domestic network. Most Delta First cabins feature recliner-style seats, premium snacks or meals, and strong Wi-Fi. On select transcontinental routes, Delta One offers lie-flat seats, giving passengers a more luxurious experience.

Key features of Delta’s First Class include:

• Recliner seats with 36-38 inches of pitch and 20.5-21 inches of width
• Delta One lie-flat seats on select routes (JFK-LAX/SFO/SEA)
• Premium snacks and meals
• Free messaging and reliable Wi-Fi
• Sky Club access for First Class passengers with certain credit cards or elite status
• Flexible ticketing with free same-day changes

Delta’s focus on customer service and flexibility makes it a favorite among frequent travelers. The airline’s ongoing investment in Sky Club lounges and onboard amenities keeps it at the top for overall satisfaction.

United Airlines: Comfort and Innovation

United Airlines is making headlines with its new Polaris Studio and “Elevated” interiors, which bring advanced seat technology and more privacy to select routes. While these new cabins are not always sold as a separate First Class product, they represent a significant upgrade for premium travelers.

United’s First Class offerings include:

• Recliner seats on most domestic routes, with generous padding and large entertainment screens
• Polaris Studio/Elevated interior with reverse herringbone layouts for more privacy (available on select routes)
• Premium meals in Polaris Studio cabins
• United Club access for eligible First Class passengers
• Priority boarding and check-in

United’s new premium seats are praised for comfort and entertainment, but availability can be limited, and food quality sometimes falls short of competitors.

These changes mean travelers will have even more choices and higher standards for comfort and service in the coming years.

Real-World Scenarios: Choosing the Right Airline
