I sat next to a UPS 757/767 pilot on a recent flight. He was a riot to talk to. Very funny and had a very, very dry sense of humor. I asked him if he was a fan of Wilson volleyballs and his comment was an emphatic "yes!" He did mention that their catering was "exceptional" and that they don't have to worry about the FAs complaining, the passengers complaining or anyone else complaining--even the mechanics.
Anyway, if you really are going the pilot route, I've heard from a couple airline pilots that cargo is the future, because "boxes always will always have to fly."
Just get used to flying at night and sleeping all day.
