Indeed, my understanding is that an expired license is not a valid form of ID.
Do you have a passport? If not, I'd get one immediately!

Wrong. The permission to drive on public streets does expire, but the mere identity verification portion of a state ID, such as a driver license, never expirers. The airline employee was full of it. The expiration date on the ID has nothing to do with who you are. It only has to do with the particular driving privilege requirements of your state. There is nothing wrong with using your old DL for ID.
