That is the instrument that I had in mind when I was thinking of the ones that musicians buy tickets for, but I couldn't think of a name that had a collision with it.

I had heard that some airlines may have tried to discourage the practice but this is the first I heard about such measures.

Seems common for some travelers to book tickets ie. Tuba, Lastname. https://www.flyertalk.com/forum/united-mileage-plus-pre-merg...
