About this corridor

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 San Diego

San Diego International is 3 miles from downtown San Diego — the second most central US airport after BOS. MTS Route 992 runs from the terminals directly to downtown San Diego in 15 minutes for $2.50. Fares from US East Coast cities peak around Comic-Con (mid-July) and the San Diego Padres' major series; September–November is consistently the cheapest window with the best weather.
