Flying from Denver International
Denver International sits 25 miles northeast of downtown Denver — a deliberately remote site that allows for six runways and almost unlimited expansion. The A Line commuter train runs every 15 minutes from the airport directly to Union Station downtown in 37 minutes for $10.50. United dominates the schedule with its largest non-Newark hub; Southwest and Frontier add heavy domestic capacity. Snow disruption is common between November and March, but the airport's ground-stop policy is faster than ORD's.
