TSA security checkpoints
At Portland International Airport, security checking is done by Transportation Security Administration. Passengers, willing to fly from the airport, must have an airline boarding pass and government-issued photo ID, passport, or driver’s license. Security checkpoints are both in the north and south sections of the terminal. Passengers can choose between them based on how short the queue is at each security checkpoint.
Portland International Airport recommends its passengers to be at the airport an hour before departure. At the security desks, TSA employees will ask passengers to remove shoes, belts, jewelry, and watches and put them in the plastic bin for the screening. Passengers are also obliged to put away their electronic devices from the carry-on bags. Every person goes under the full-body scanner too. PDX administration advises every passenger not to carry sharp items, scissors, baseball bats, alcohol, glass bottles, etc. in the carry-on bag.
Concourse B and C security checkpoints open at 4 am and close at 10 pm. But concourse D and E checkpoints are open 24 hours, and passengers can use it anytime.
Frequent flyers who are in Customs and Border Protection Trusted Traveler program, can use a Pre-Check Lane. This means that in the Pre-Check area, passengers are not asked to remove shoes, belt, jacket, laptop from the carry-on bag. But there still is a restriction on liquids and sharp items.
