It was just a few years back that I was still routinely using the airside mailbox at ORD T5, but it’s been at least three years since I last used it. For a while it was a regular blue mailbox but then it was just the letter slot in the wall.
Not sure why many other US airports got rid of airside mail facilities, but obviously some managed to keep around such an option airside for many years after 9/11.
