If you need to drop those postcards in the mail from Graceland, you have some options.
I couldn’t find anything in text. The terminal map shows the only mail drop, which I’m gathering is pre-security: Concourse A, baggage level – across from pay phones. That’s literally the best information I can give, as the maps are not very good either.
