People can say what they want. However, if I order a latte at Starbucks I can say I'm having sex, but it doesn't make it so.
I thought the term originally applied only to upgrades on the aircraft. In any case, I consider only upgrades on the aircraft to be "battlefield" upgrades. An upgrade at the gate would be a "gate upgrade" or "upgrade at the gate."
