American Airlines has placed its first retrofitted Boeing 777-300ER into commercial service on a New York-Buenos Aires flight, beginning a fleetwide shift away from a separate international first-class cabin. The redesigned aircraft has 144 premium seats, up from 116, lifting premium inventory to about 44% from 38%. The 20-aircraft 777-300ER fleet is scheduled for completion sometime in 2027. The new layout includes 70 Flagship Suite business-class seats with sliding privacy doors, 44 Premium Economy seats and 30 Main Cabin Extra seats, while the remaining Main Cabin has 186 standard seats. Flagship First will no longer be sold on 777-300ER flights for travel beginning November 19, making American the last of the three largest U.S. network carriers to eliminate a separate international first-class cabin. American said in 2022 that customers were not buying the product and that reallocating space to business class would better match demand. Premium travelers generated nearly half of American's ticketed revenue in the second quarter while occupying about 30% of its seats. The aircraft also receive upgraded inflight entertainment, and AAdvantage members will have access to free high-speed Wi-Fi. The move reflects a broader airline-industry push toward premium products as carriers pursue higher-spending customers. American's 777-300ERs serve markets including London, Tokyo, Sao Paulo, Buenos Aires and Sydney, and the carrier plans a similar but smaller configuration for incoming Airbus A321XLR aircraft.
