777-200ER / 777-300ER (sliding-door World Business Class): 10/10 for the seat. The door is documented for the refitted 777 product. Do not apply it to every 787 or A330. Check the flight's seat map and ticket type; lounge access and baggage can differ by fare brand. Recorded August 30, 2026.
A330-200 / A330-300: 5/10 for the seat. 2-2-2 lie-flat: the window seat requires stepping over a neighbor. Recorded August 30, 2026.
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.

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.
