Crazyboi, you're not Yo-Yo Ma are you? My dad has a CD entitled 'Travels With My Cello', and the cover shows him sitting in a 747 cabin, First Class seats, just as you described, with the cello buckled in next to him. After some research I was able to tell my dad that it was a BA 747 cabin, at which point he began to think that son needs to get a life
Some while back I read about a priest who travels with an icon (statue of the Virgin Mary) who gets her own seat. Not sure what happens in the event of a stigmata!
