OK, I give up, ATA?

It somehow works out to be "Airline Travel Approved" or something like that.

Airlines won't be responsible for delicate items checked as baggage,
like guitars or test instruments, unless they're in a proper case. Blow
molded and standard fiberboard instrument cases aren't usually acceptable.

Sometimes, a flight crew will let you stick guitars in the passenger
deck closets, but you can't count on it.
