I have been on both sides of the fence.
I was 460 lbs 12 months ago ? I have lost over 200 LBS so far.
Not all ?Fat people? are fat by choice. My problem was 100% medical and I tried everything to lose it.
Many times I bought 2 sets when I traveled and did on my own.
I?m not against the airline wanting to charge for 2 seats for someone that don?t fit because it is unsafe and cuts into the person next to him or her.
