Official Information

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.
