Cheap One-Way Flights from Las Vegas

Las Vegas is a Spirit hub and one of the most competitive domestic markets in the US — airlines fight hard for tourist traffic, which means ultra-cheap one-way fares on popular routes. Southwest, Frontier, and Spirit all have major operations here. International options are limited but growing — Volaris runs cheap routes to Mexico, and seasonal European charters pop up. For the lowest fares, book midweek flights outside holiday periods.
