From their Services and Amenities Web page:
U.S. Mail Drop Boxes are located throughout the Second Level of the terminal pre-security.
Unfortunately, there’s not any other information. The maps are non-existent (in fact, their shopping URL expired!). There are three separate terminals. If you have time, you’ll need to wander around the airport pre-security on the second level and find them.
Robert submitted a paper map and a wealth of information:
All mailboxes are on the second level:
- Next to Door 2
- In between Doors 5 and 6
- Between Doors 9 and 10
- Between Doors 14 and 15
- Between Doors 16 and 17
- Between Doors 23 and 24
This information may be dated as it was from a couple of years ago.
