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.
Arriving in Cancún
Cancún International is 16 km south of Cancún's hotel zone. ADO bus runs direct to the centre and the Riviera Maya for 110–230 MXN; private resort transfers cost $40–$80 per person. The route from the US is one of the busiest international corridors in the world, with daily fares from any major US hub. Hurricane season (June–November) brings cheaper fares and fewer crowds; peak demand is Christmas, spring break and US Thanksgiving.
