Check the aircraft on TAP Air Portugal
A330-900neo: 8/10 for the seat. The A321LR also flies US-Europe and runs an alternating 2-2 and 1-1 layout, so not every seat has direct aisle access on that aircraft. Recorded August 30, 2026.
A321LR: 5/10 for the seat. Solo throne seats in the 1-1 rows; the 2-2 rows require stepping over a neighbor. 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.

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.
