My mum has just offered to pay for me and a friend to go on holiday for my 21st. I'm a big girl, and so is she. (last time i was on a plane a few stone back I had quite a job getting the seat belt done, and I'm worried about not fitting now. We can't afford to pay for 2 tickets, and I'm just wondering if anyone here has been made too buy 2 in the UK? What about seatbelt extenders, do they use them here? arghh will i fit in the seat?
