American Airlines’ most premium-configured aircraft made its debut Wednesday, flying from New York to Argentina.
The newly retrofitted Boeing 777-300ER features 70 Flagship Suite business-class seats with privacy doors, 44 premium economy seats, and 30 extra-legroom Main Cabin Extra seats. Combined with 186 standard economy seats, the aircraft can carry 330 passengers.
American’s current 777-300ER configuration seats up to 304 passengers, including eight Flagship First seats and 52 in business class.
“Our Flagship aircraft represents the next evolution of premium travel at American,” Nat Pieper, the airline’s chief commercial officer, said in a news release.

Flagship Suites feature sliding privacy doors, additional storage, and a chaise lounge seating position. Customers also receive a mattress pad, a dual-sided cool-touch pillow, and an amenity kit.
Passengers traveling in the Flagship cabin receive priority check-in, security, boarding, and baggage handling. The experience also includes access to American’s Flagship lounges where available and multicourse dining on board.
Premium economy seats are equipped with wireless charging and USB-A and USB-C power. Passengers throughout the aircraft have access to updated inflight entertainment.

American is also installing high-speed Wi-Fi across its 777-300ER fleet, with complimentary access planned for AAdvantage members.
The Flagship Suite product is already available on American’s newly delivered Boeing 787-9 aircraft and Airbus A321XLRs. The carrier plans to retrofit all 20 of its 777-300ERs by the end of 2027.
American currently deploys the aircraft on long-haul routes to destinations including Sydney, Tokyo, Buenos Aires, London, and São Paulo. The first retrofitted jet entered service Wednesday between New York-JFK and Buenos Aires.
The cabin overhaul will also spell the end of Flagship First, currently the only long-haul international first-class product offered by a U.S. airline. American will stop selling Flagship First on its 777-300ERs for travel beginning Nov. 19.
The product will remain available on select transcontinental flights for several more months before being withdrawn for travel beginning March 28, 2027, as additional A321XLRs enter service.
