American Airlines and United have both spent the past two years developing their most expensive business class products ever, then put them head-to-head on the same transatlantic corridors. The twist: both picked the identical seat — the Adient Elevate Ascent — from the same manufacturer. Everything passengers notice as different comes down to how each airline deployed it.
United concentrated the Elevate Ascent into eight Polaris Studio suites at the front of its 64-seat 'Elevated' 787-9 business cabin, creating a genuine two-tier product. Studio seats are roughly 25% larger than standard Polaris, carry a 27-inch 4K OLED screen (claimed as the biggest on any US carrier) versus 19 inches behind them, and come with an extra ottoman seat, exclusive dining and caviar service. Six of the eight seats work as proper two-person spaces. United charges an additional seat selection fee for Studio on top of a Polaris fare.
American took the opposite path, spreading the same seat across all 51 business positions on its 787-9P — eight Flagship Suite Preferred plus 43 standard suites with identical 17.5-inch screens. The Preferred tier's main perks are cabin position and, on the 777-300ER, a bed just one inch longer than standard. Whether travellers will pay a premium for that is the open question; a surcharge for Preferred seats is reportedly expected as the rollout matures.
There's a shared embarrassment too: both airlines launched their flagship suites with the headline privacy doors installed but unusable, apparently awaiting certification rather than held up by manufacturing. Both flew anyway rather than park revenue-earning aircraft. Rollouts continue regardless — American had about 14 787-9Ps in service by May 2026, with Flagship Suites also going onto its A321XLRs and retrofit 777s, while United is fitting the Elevated interior to all future 787 deliveries.
For travellers, the practical picture: United's Elevated 787-9 launched on San Francisco–Singapore on April 22, 2026, then San Francisco–London from April 30, and now flies all three daily SFO–Heathrow rotations. American has flagged Chicago O'Hare–London as an early Flagship Suite route, so the two products compete on the same corridor. If you want the genuinely swankier seat, book United Studio — and book early, since it's only eight seats per plane. If you simply want a consistent premium experience anywhere in the business cabin, American's approach means even the last row gets the same hardware. Either way, check whether the privacy doors are actually working before you count on that enclosed-suite feeling.
