I am hoping that after discussion with the cabin crew, your near neighbour was invited to use their own row for exit. One tactic is to scatter some possessions or bags along your side of the seat to make it tricky for people to clamber over into your row. I guess the other argument is that it is shared space on public transport, no one "owns" anything here. Well, apart, ideally, from a bit of commonsense and mutual respect, but that's often in short supply.

Anyway I needed to put that map since this forum is extremely good at illustrating how to sit a little further forward on the aircraft. Quite a number of experienced travellers here wouldn't have a clue about this, and so if you stick around here long enough you need never encounter this problem again!
