Flying from Harry Reid International
Harry Reid International sits a five-minute drive from the south end of the Las Vegas Strip — closer to its city centre than virtually any other major US airport. The terminals don't connect to rail; airport shuttles, taxis and rideshare handle the bulk of arriving traffic. Southwest is the largest carrier with its biggest non-base operation here, and Spirit, Frontier and Allegiant make Las Vegas one of the cheapest US fly-in destinations from anywhere in the country.
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).
