I have a question about seating that I'm sure other airlines have addressed. I know that a person in a wheelchair cannot sit in the exit row. But suppose a person who'll need wheelchair assistance unknowingly books a seat in the exit row. How do flight attendants address the problem? Do they simply ask for someone in the equivalent style of seat (extended leg or preferred-I forget which) to trade? Do they randomly take someone from a non-exit row to switch? I know that currently it isn't a problem (I'm in a wheelchair, and once when I got on, I must have looked like I was headed for the exit row, and a flight attendant quickly appeared, seemingly out of nowhere, with a panicked look on her face to remind me "No exit row")
