This question already has an answer here:
My mother is going on a flight with United Airlines. I'm sort of nervous for her because she hasn't really been on a airplane since she gained much weight. She's pushing 400 pounds, even if it doesn't seem that, (her body seems smaller then her actually weight). I don't want her go to the airport and be humiliated over the fact of some random employee making her buy an extra seat, or anything.
What's the cut off for being to big?
Do you think she will fit or should I buy her an extra seat in advance?
