Thanks to Robert for submitting information from their web site and confirming it!
The airport’s Passenger Services page is fairly descriptive:
U.S. Postal Service mailboxes are located on the ticketing (second) level. One is located at the exit from the International Arrivals Lounge from the A Concourse and another is near the entrance to the B gates, next to the American Airlines check-in counter. Both are outside of security.
A Federal Express drop-off box is on the ticketing (second) level near the entrance to the A gates, next to the United Airlines check-in counter.
A United Parcel Service (UPS) drop-off box is on the ticketing (second) level near the entrance to the B gates.
The Interactive Terminal Map makes it pretty clear where they are as well, and provide a better way markers for navigation:
- Terminal A: Beside the United Check-in counters.
- Terminal B: Beside the American Check-in counters.
