The airport site mentions a US mailbox, but nothing about it.
Saul wrote in and said there’s a mailbox on the curb to the left of the terminal entrance. Thank you sir!
Google Maps shows it clearly, assuming there is one terminal entrance (it looks to be that way).
Fair Warning: When I checked the airport site, it mentioned there was a significant expansion of the terminals and roads were being re-routed. This information may change sooner rather than later.
