Flagstaff, Arizona – United Airlines will begin twice-daily nonstop service from Denver to Flagstaff Pulliam Airport next summer, adding direct competition at a regional gateway long dominated by American Airlines. The move follows Delta Air Lines’ announcement of its own twice-daily flights from Salt Lake City by less than two days. Both carriers will operate the 50-seat Bombardier CRJ-550 on the routes, giving travelers easier access to Northern Arizona’s major attractions without routing through Phoenix. ([1])
New Nonstop Options From Major Hubs
United’s service from Denver International Airport is scheduled to start August 10, 2027. Delta’s flights from Salt Lake City International Airport begin earlier, on June 7, 2027. The aircraft configuration on both routes includes 10 first-class seats, 20 extra-legroom economy seats, and 20 standard economy seats. These additions mark the first time in years that travelers from two major western hubs will have direct flights to Flagstaff. United previously operated the Denver route from 2019 until 2022 before suspending it.
Airport Competition and Longtime Dominance
American Airlines has served Flagstaff for decades from its Phoenix hub and, since 2018, from Dallas-Fort Worth. The carrier remains the primary operator at the airport, which sits roughly two hours north of Phoenix Sky Harbor. The new entries from United and Delta introduce meaningful competition at an airport that has historically lacked options from other major carriers. Flagstaff Pulliam also serves Northern Arizona University and functions as a convenient entry point for visitors exploring the region.
Grant Support and Regional Access
Flagstaff recently received an $800,000 federal grant aimed at encouraging airlines to add flights to either Denver or Salt Lake City. The incentives align with the timing of both announcements and underscore efforts to improve connectivity for a market near Grand Canyon National Park and Sedona. The airport’s location positions it as a practical alternative to longer drives from Phoenix or more distant gateways for travelers targeting those destinations.
| Carrier | Origin | Start Date | Frequency |
|---|---|---|---|
| Delta | Salt Lake City | June 7, 2027 | Twice daily |
| United | Denver | August 10, 2027 | Twice daily |
The paired announcements signal a shift in service patterns at Flagstaff Pulliam that could benefit both leisure travelers and the local economy in the coming years.
