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, but as noted below this looks to be post-security.

User-Submitted Information

Jason sent an email in 2023 noting the probable location of the mail slot:

The mail slot is inside security in the McNamara (Delta) terminal. It is at the central point of the A concourse near the security checkpoint and the Skylink stop. Standing at the fountain, facing toward the Skylink, it is to the right side of the departure monitors on the wall underneath a mounted AED cabinet.
