American just gave its largest Boeing jets a major business class makeover. See how the cabin changed.

American Airlines’ largest Boeing widebody plane just got a major makeover.

On Wednesday, the airline unveiled its new Flagship business class suites for its 20-strong Boeing 777-300ER fleet.

American said it’s the most premium-packed jet in the US, with 144 premium seats in total: 70 business-class suites, 44 premium economy seats, and 30 extra-legroom Main Cabin Extra seats.

The 777-300ER is the third aircraft type American has fitted with the upgraded Flagship Suite.

The cabin debuted on newly delivered Boeing 787-9s in June 2025 and later launched on the Airbus A321XLR in December 2025.

Customers experienced the new Flagship interior for the first time on a flight from New York-JFK to Buenos Aires on Wednesday, and it features a lot of new perks compared to the old version.

Business-class finally has doors, as well as more storage, more space, and better entertainment.

Perhaps most notably, it doesn’t have Flagship First, the last of its kind among US carriers.

The distinctive cabin will no longer be available for booking from November 19 amid low demand and customer preference for a better business class.

American — and the broader airline industry — continue to bet on premium travel as passengers remain willing to pay more for added comforts.

Earlier this year, United Airlines announced a new “Elevated” interior for its Boeing 787s, featuring 99 business-class and premium-economy seats.

Delta has also announced new cabins for its future Airbus A350-1000s, set to debut in 2027, with premium seats making up 50% of the jet.

Business-class seats are highly profitable and account for a significant part of airlines’ ticket revenue, helping pad their bottom lines even as some consumers pull back on spending and the conflict in the Middle East drives up fuel prices.

In the airline’s July earnings call, American chief commercial officer Nat Pieper said that much of that revenue is from affluent customers, saying, “Nearly 60% of our revenue comes from households making $150,000 or more, and so that’s demand that’s more likely to hold up through economic uncertainty.” Here’s a closer look at how American is capitalizing on the premium boom, and how its new Flagship Suite compares to the old one.
