For those living near any of these 160-plus gateways, the choice of departure city comes down to proximity and schedule frequency, since the sheer number of nonstop options means most Americans are within a short drive of a direct flight to Denver.", "methodology": "The U.S. departure cities with nonstop service to this destination and their weekly frequencies come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI).
