The premier international flight is United Airlines' nonstop Denver to London flight. Other international airlines include Air Canada, Mexicana, and Martinair, a European charter carrier. DIA is also the hub for regional and commuter flights, primarily on United Express, to destinations throughout the Rockies and the Southwest. Transportation between downtown and DIA is costly by cab and time consuming by car if you include time spent searching for parking. In the best traffic and weather situations, allow 30 minutes to make the trip.
Public transportation is the cheapest option.
