JetBlue doesn't have a traditional "office" in Denver, but operates at Denver International Airport (DEN) in Concourse A, on Level 5 for ticketing and departures, with customer support typically handled online, via phone (1-800-JETBLUE), or through the airport's general information booths. You'll find JetBlue's ticket counters in the central area of Level 5 for check-in and assistance at DEN.
