PDX drew rave reviews for its "frustration-free" security checkpoints, affordable retail options, and diversity of food and entertainment.

PORTLAND, Ore. – For the sixth year in a row, Portland International Airport has been recognized as the best airport in the United States.

"It may not be the newest or the largest on this year's list, but 'user-friendly' PDX has garnered more than its fair share of enthusiastic fans – and not just for its famous #pdxcarpet," wrote Travel + Leisure's Sarah Bruning in an article announcing the results of its readers' ratings of US airports.

Factors that went into an airport’s rating were its accessibility, check-in, security, restaurants and bars, shopping, and design.

"[Portland International Airport] excelled in all these areas, bringing together a seamless curb-to-plane experience, standout local vendors, and a community-minded sensibility that impressed travelers," Bruning wrote.

Humbled to be recognized by @TravelLeisure for the sixth year in a row as America's Best Airport. Hats off to the more than 10,000 PDX employees that made this possible! #PDXPeople #TLWorldsBest https://t.co/CEX7iZZmEO — flypdx (@flypdx) July 10, 2018
