Moveable-armrest seats
If you have mobbility issues you may want to use a seat with a moveable aisle armrest. On most of our aircraft these are at every seat in the Economy cabin that is not at bulkhead or exit. On some of our 747-400 fleet, (5 aircraft primarily operating our Gatwick, Manchester and Glasgow routes) the moveable armrests are only at rows 26C-27C/29C-37C/30H-37H and 31DG-37DG.
On our A330 fleet our Premium Economy seats on the left side of an aisle have moveable armrests.
Fixed-armrest seats
Seats on economy exit rows, bulkhead seats (where there is a wall in front of you), rows 60 D,E,F,G on the Airbus A330 and all seats in Premium Economy (not in the A330 fleet) and Upper Class have fixed armrests.
