Just before anyone leaves a snarky comment, I'm fat and aware of it. I am not in denial and I'm working on it.
I've just been invited on an exciting trip to Moscow with my best friend flying with British airways. I told her I was hesitant to say yes as I'm a size 24 and I worry that I won't fit in the plane seat. She told me I was worrying unduly but it's been a while since I've flown and was much smaller then
For reference I can fit in London Underground seats (the ones with fixed arms) and a seatbelt is not a problem.
Aibu to worry? I don't mind asking for an extended belt but would be mortifying to not fit in seat or be asked to buy another ticket
