Thinking about this some more, how is it that he has flown so much in TATL economy, yet he has not had to sit next to a large person overflowing into his seat, a belligerent yelling drunk, a person behind him objecting to his reclining on an overnight flight or a person who has not bathed in a week? Let alone that at his age he doesn’t have lots of aches and pains after sitting upright for 8 hours. These are all the reasons I went from flying international economy when I was younger to figuring out how to get upgrades and saver awards.
