The business seats being compared

These are each airline’s best-scoring documented business aircraft. The fare grid does not identify aircraft, so the seat below is not promised with any fare in the table. Service and food require a separate firsthand review.

A350 Next (Recaro CL6720): 10/10 for the seat. Only a small part of the A350 fleet has the door. Standard A350s and the A330 use the older Stelia Solstys seat: still 1-2-1 and still lie-flat, but open to the aisle. Recorded August 30, 2026.

A330 / standard A350 (Stelia Solstys): 8/10 for the seat. Same 1-2-1 lie-flat layout, no closing door. Recorded August 30, 2026.

Check the aircraft on United

777 / 787 (Polaris): 8/10 for the seat. The 767-300ER and 767-400ER run an unusual 1-1-1 layout with no paired seats at all, which is more private again. Select 787-9s add Polaris Studio suites with doors in the front rows. Recorded August 30, 2026.

767-300ER / 767-400ER: 8/10 for the seat. 1-1-1: no adjacent pairs anywhere in the cabin, the most private Polaris layout. Recorded August 30, 2026.

Compare the fares and the routing

Each row compares the same airports, cabin, travel dates and observation date. It can still compare a nonstop against a connection. Journey times, aircraft, baggage allowances and change rules were not recorded with these fares; check those before treating the price difference as a saving.

Your airport missing? Check the full route tool for the airlines we observed there. Confirm current fares, journey time, baggage and ticket rules before booking.

Before paying for the ticket

  • Check the exact operating airline and seat map on every long flight, including the return. An airline name or business-class label alone does not guarantee a flat bed or aisle access.
  • Compare total journey time and connection length. A lower fare may buy a much longer trip.
  • Reprice with your bags, preferred seats and change rules included. These observations do not establish that the tickets have identical restrictions.
  • Check other airlines on the route. Being cheaper than the other airline on this page does not establish the cheapest fare in the market.
