Getting around PDX
Terminals
One terminal with Concourses B, C, D and E.
Changing terminals
The rebuilt main terminal opened in 2024. Its south checkpoint serves Concourses B and C and its north checkpoint D and E, but both lead into one secure area, so you can walk to any gate without screening again. The longest gate-to-gate walks take 15–20 minutes.
Customs and international arrivals
Arriving from abroad, you clear U.S. Customs and Border Protection (CBP), collect your checked bags, drop them at the recheck belt and go through TSA security again before your connection. International flights use Concourse D.
Tips for connecting at PDX
- •Alaska's new Portland lounge opened in June 2026 at the top of Concourse C.
- •The MAX Red Line light rail stops right at the terminal.

PDX connection FAQ
Airlines set their own official minimums at PDX and only sell connections that meet them, so a one-ticket itinerary is always "legal". In practice we recommend at least 50 min for a domestic connection and 2 h 20 min after an international arrival.
