Frontier launches Dulles-to-Vegas service with introductory $15 one-way fares

CHANTILLY, Va. — Low-cost carrier Frontier Airlines is launching service to Las Vegas and 13 other cities from Dulles International Airport.

The Denver-based airline announced Tuesday that service will begin from Dulles in August and September.

Last month, Frontier announced a new fare structure that pushes it further toward the model of ultralow-cost carriers that charge deeply discounted base fares, with additional fees for items like use of overhead bins, or extra leg room.

Nonstop service to Atlanta; Charlotte, N.C.; Orlando, Fla.; Minneapolis/St. Paul; Chicago-O’Hare and Tampa, Fla. begins Aug. 19. Service to Cincinnati, Ohio; Detroit; Fort Lauderdale, Fla.; Las Vegas; Memphis, Tenn.; Fort Myers, Fla.; St. Louis and St. Augustine/Jacksonville, Fla., begins Sept. 8.

The airline kicked off service with a 12-hour fare sale Tuesday that clogged the website with travelers seeking $15 one-way fares.
