Sometimes you get lucky. I was carrying on a guitar (admittedly this was years ago) and the attendant was demanding that I check it which, having heard the horror stories, I was very reluctant to do. The captain asked, "What have you got in there?" Martin D-28, I replied. He said, "I'm a player myself. That's a nice guitar. Why don't you let me carry that up in the cockpit for you?" Handed it out to me at the end of the flight.
There have never in history been so many opportunities to do so many things that aren't worth doing. - William Gaddis
