American Airlines has unveiled all-new Flagship Suite and Premium Economy seats that are set to debut on the airline’s long-haul fleet starting in 2024.

The new Flagship Suite seats will replace the current First and Business cabins and will feature sliding doors, a chaise lounge seating option and more personal storage space.

American’s move will see the carrier also increase the number of spacious seats on aircraft, with Business and Premium seating in American’s long-haul fleet growing by more than 45 percent by 2026.

The new Flagship Suite seats will be included on all Airbus A321XLR and Boeing 787-9 deliveries beginning in 2024.

American’s Boeing 787-9 aircraft will have 51 Flagship Suite seats and 32 Premium Economy seats, and the airline’s Airbus A321XLR aircraft will feature 20 Flagship Suite seats and 12 Premium Economy seats.

“We are enhancing the customer experience across their entire journey with American,” American’s Vice President of Customer Experience Julie Rath said.

“The arrival of new long-haul aircraft and the customized seat design of the Flagship Suite seats will offer customers a truly private premium experience on our long-haul fleet.”

When the new deliveries start in 2024, American will also refresh its Boeing 777-300ER fleet with a new luxurious interior, elevating the inflight customer experience on long-haul international routes.

American’s Boeing 777-300ER aircraft will feature more premium seats than its current design, with 70 Flagship Suite seats and 44 Premium Economy seats.

The carrier will also retrofit its Airbus A321T fleet to align those 16 aircraft with the rest of its A321 fleet.
