CAPETONIAN.
If wife and I travelling together, we always try and get opposing aisle seats. Long Haul means having to get up at least once for loo, and I like to walk about and not risk DVT. I have long legs, and, particularly with South African Airways towards Christmas, find that I can have more leg room by using some of the aisle room, provided I don't trip up the FA, of course. Wife has the same argument.
I do, however like a window seat, but find the inconvenience of getting up and climbing over sleeping people not worth the view [except coming in to Cape Town of course.]
