Same aircraft, wildly different flight. A comparison of Boeing 787-9 business cabins shows five airlines packing at least 40 premium seats into the Dreamliner, and the spread tells you a lot about how differently carriers bet on long-haul travel.

United Airlines tops the list. Its "Elevated" 787-9 carries just 222 passengers, but 64 of them sit in Polaris suites — including eight larger Polaris Studio suites with sliding doors, a 27-inch 4K OLED screen, a companion ottoman and wireless charging. Add 35 Premium Plus seats and nearly 45% of the aircraft is premium. The type started flying San Francisco–Singapore in April 2026, moves to Houston for São Paulo, Sydney and Tokyo routes from October 2026, and United wants 33 of them in service by 2028.

Japan Airlines comes close with up to 52 Sky Suite III seats on its 203-seat layout — a reverse-herringbone design where every seat angles toward the window with direct aisle access and a bed of roughly 78 inches. JAL also flies an older 195-seat version with 44 seats in a 2-2-2 layout, plus a third low-density configuration, so it's worth checking which jet you've booked.

American Airlines' premium-heavy 787-9P has 51 business seats, every one with a door: eight Flagship Suite Preferred seats at the front of each cabin offer up to 19% more bed space and 42% more living area than the standard Flagship Suites. It entered service in spring 2025 on transatlantic routes from Chicago and Philadelphia. The catch: American also flies a 285-seat 787-9 with only 30 business seats — a completely different experience.

ANA's 787-9 carries 48 seats in The Room FX, developed with Safran Seats and Acumen, with doors, 24-inch 4K screens, and a pre-recline that creates a sofa-like position before flattening into a 76.5-inch bed. Rollout begins on major long-haul routes from 2026 — but only some ANA 787-9s get it; others use the older Business Staggered seat.

Qantas rounds out the list with 42 Thompson Aero Vantage XL seats on 236-seat aircraft, split between a 30-seat forward cabin and a 12-seat rear cabin. Doors are coming, though: Qantas advertises suites with sliding doors on deliveries from fiscal 2028.

Why it matters: the aircraft type on your booking tells you almost nothing about the cabin. The same 787-9 can be a 64-seat premium flagship or a 285-seat workhorse with 30 business seats. Before spending miles or money on a long-haul flight, pull up the seat map and check the business-class count and layout — five minutes of checking can be the difference between a sliding-door suite and a conventional recliner.
