United lists Flagstaff-Denver nonstop for 2027 (azdailysun.com)

United Airlines has listed nonstop flights from Flagstaff Pulliam Airport to Denver International Airport beginning Aug. 10, 2027, with two daily departures each way. The route, previously operated from 2019 to 2022, comes days after Delta announced nonstop service to Salt Lake City starting June 2027. Flagstaff received an $800,000 federal grant to support new nonstop service to either Denver or Salt Lake City, and city officials say discussions with carriers are ongoing.
