Exploring Flagstaff from the Pacific Northwest

Traveling from Portland to Flagstaff carries you from the Willamette Valley up to a mountain town perched at an elevation of 7,000 feet. Departures leave from Portland International Airport (PDX) and arrive at Flagstaff Pulliam Airport (FLG). Because Flagstaff is a regional destination, itineraries on this route include a connection at a major hub in the Mountain West or Southwest.

Unlike much of Arizona, Flagstaff features a crisp, four-season mountain climate with snowy winters and mild, sunny summers. Visitors can explore the charming downtown along historic Route 66, dine at cozy craft brewpubs, and take in the vibrant culture of neighborhoods like Southside. Flagstaff is also the world's first International Dark Sky City, making evening visits to Lowell Observatory a highlight alongside outdoor excursions into the surrounding Coconino National Forest.

Money-saving tips for this route

Book your tickets four to six weeks in advance to secure convenient layover times into regional Flagstaff Pulliam Airport.
Choose Tuesday or Wednesday departures to take advantage of lower midweek fares and lighter airport crowds.
Pack versatile layers, as mountain temperatures in Northern Arizona can drop dramatically once the sun goes down.
Consider comparing flights into Phoenix Sky Harbor if you desire additional flight frequency and are comfortable with a two-hour drive north to Flagstaff.
