so first on the aircraft, so first off the aircraft
EH?...How do you work that one out then? Are you suggesting that every cargo compartment has an "IN" door , and an "OUT" door?....so the loaders push the first bag all the way to the out door and pile the others behind? NO
First on ,is, logically, last off.
Sorry, just a typo, I meant last off the truck, last on the aircraft, first off.
There must be some logical process to bag handling, and more often than not I find that if I checked my hold bag ridiculously early then it's one of the first out, whereas travelling companions who checked in much later had to wait longer for theirs.
