Notes

Seat scores are SeatMap's rating of every seat out of 10, from its measures and what sits around it. Good or better means 7 and up.
Legroom, width and recline are the airline's published figures for each cabin. A range means the seats in that cabin differ.
Seat maps show the aircraft the airline has planned for this flight on Tue, Nov 3, 2026. Airlines can change the aircraft before departure.
Open and taken seats, live from the airline, come with SeatMap Pro on each flight's own seat map.
