Fly from Washington DC to Las Vegas for $225 round-trip, including all taxes, as part of Frontier's new nonstop service.

Service begins on September 8, though we found the above $225 fare departing IAD on Monday, September 15, returning from LAS on Friday, September 26. A lengthy trip, but one that will surely work for some folks out there. Other dates available for travel through October 9.
