American Airlines boosts premium seating on 777 jets as upscale travel grows

American's move is part of a wider push by U.S. carriers toward premium travel. Revenue from higher-end products has been growing faster than more price-sensitive offerings at some of the largest airlines, reflecting a widening divide as wealthier customers keep spending while budget-conscious travelers pull back.

The shift is also reaching airlines traditionally built around lower fares. Southwest Airlines is evaluating products once associated with network carriers, including airport lounges, transoceanic flying and more premium seating. Frontier is adding first-class-style seats, while JetBlue is expanding its premium offering with airport lounges.

American's 777-300ERs serve long-haul markets including London, Tokyo, Sao Paulo, Buenos Aires and Sydney. The retrofitted aircraft will also offer upgraded inflight entertainment, while members of American's AAdvantage loyalty program will have access to free high-speed Wi-Fi.
