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 Toronto
Toronto Pearson is 22 km northwest of downtown Toronto, with the UP Express train reaching Union Station in 25 minutes for CA$12.35. Air Canada is the dominant carrier; US carriers serve YYZ heavily as the largest cross-border destination. Fares from US East Coast and Midwest are competitive year-round; peak demand is around Caribana (early August) and the Toronto International Film Festival (early September).
