Detroit Metropolitan Wayne County Airport (DTW)

Thanks to Robert for supplying a link to me!

Official Information

It’s not on a map; it’s only in their frequently asked questions near the bottom of the page:

At the McNamara Terminal, there is a mail slot located under the tram in the Central Link. We do not have a mailbox at the North Terminal.

No word if this is pre-security or post-security.
