Flying from New York LaGuardia

The Q70 Limited bus runs free from each terminal to subway connections at Jackson Heights and Woodside; rail directly to LGA does not yet exist (the AirTrain proposal was cancelled in 2023). Operations are domestic-only with limited transborder service. Delta, American and JetBlue have the largest schedules; Southwest and Spirit add ULCC capacity.
Arriving in Denver
Denver International is 25 miles northeast of downtown Denver — the most remote big-city airport in the US, deliberately sited to allow for unlimited expansion. The University of Colorado A Line commuter train runs from a dedicated station every 15 minutes to Union Station in 37 minutes for $10.50. Snow can disrupt operations from November through April; Denver fares are cheapest in shoulder seasons (April–May, September–October).
