Explaining luggage regulations to passengers can be aggravating for flight attendants. One day a woman tried to board with an enormous bag.
The lead flight attendant told her why it would not fit, but the woman argued that her bag was a carry-on because it had wheels and a handle.
Without blinking the attendant said, “My car has wheels and a handle, but that doesn’t make it a carry-on. “
