I booked a trip on Copa, and saw the exit seats are available to select at no extra charge. Two quick questions:

1. I am taking an overnight flight on the 737-700 and seats 18A and 18F are available (see seat map). I usually prefer aisle seats to be able to get up without disturbing anyone, but window seats have the perk of being able to lean against something. Does anyone know if I would be able to get out of row 18 without disturbing the aisle and middle passengers, or perhaps walk up to row 17 and walk out there if the leg room is larger. If so, that would be the best of both worlds!

2. Similar question on the 737-800. Is the leg room in aisles 17 or 18 large enough to permit window/middle passengers to get out without having others get up?

Thanks!
