Question

I will be traveling with my grandfather, so is overweight. I was wondering which airline had the most comfortable seats/seatbelts for overweight passengers?

the choices are between United and American.

Answer 1

There won't be much a difference, but you can check airline seat sizes and seat pitch (legroom) on this website:

All airlines carry seat belt extenders for passengers who can't fit into the regular seat belts. Good luck.

Answer 2

They should all be the same.  No major difference if any.  You can check out http://www.seatguru.com.  United does have on some flights Economy Plus seating.  That gives you an extra 6" of legroom.  Those are usually given to their frequent fliers or those who pay extra.
