American Airlines has put its first retrofitted Boeing 777-300ER into commercial service, with the redesigned aircraft making its debut on the New York JFK–Buenos Aires route on 2 September 2026. The new configuration places the airline’s Flagship Suite at the centre of its long-haul premium cabin.

The aircraft has 144 premium seats: 70 Flagship Suite seats with privacy doors, 44 Premium Economy seats and 30 Main Cabin Extra seats. The Flagship Suite includes lie-flat seating, additional personal storage and a chaise-lounge position, with wireless charging and other features carried across American’s newer premium aircraft.

For travellers booking Premium Economy, the redesigned cabin adds sculpted headrests, adjustable calf and footrests, enhanced storage, wireless charging and USB-C and AC power. All 20 Boeing 777-300ERs in American’s fleet are scheduled for the new premium configuration, although the airline has not specified in its latest announcement that all 20 will be completed by a particular date in 2027.

The aircraft currently operates on American’s long-haul network including London, Tokyo, São Paulo, Buenos Aires and Sydney.

For premium travellers, the key change is the withdrawal of Flagship First from the 777-300ER. It will no longer be available for travel beginning 19 November 2026. The change applies specifically to this aircraft type, rather than signalling the disappearance of First Class across the wider airline industry.
