Thanks for combining the threads, I hadn't seen this one. I'm feeling very insecure right now. I am flying from Calif to Winnipeg next week, and am wondering if Canada Airlines will want more money once they see me. I know it's not comfortable to sit next to a large person, but it's also not comfortable to sit next to someone holding a crying child for hours. Or someone who goes to the bathroom every 5 minutes and has to climb all over everyone. Most people are very gracious and I've never had a problem in the past flying so it is really bugging me. It's always hard wondering if you're going to fit in the seats, chairs, in whatever venue be it a concert, restaurant, movie etc. I hate feeling insecure about this crap.
