$15 Flight? Frontier Airlines Offering Cheap Flights From D.C. In 12-Hour Flash Sale

Frontier Airlines announced a flash sale on Tuesday, offering ridiculously cheap flights to and from Washington Dulles International Airport (IAD). The low-cost service from the D.C.-area airport will cost just $15, including taxes and fees, to 14 destinations.

To welcome Frontier to Dulles, the carrier announced the 12-hour flash sale for $15 fares on the new routes. The sale kicked off at noon EST on Tuesday and will run through 11:59 p.m. EST. The 14 destinations included will be nonstop flights to:

Atlanta; Charlotte; Chicago-O’Hare; Cincinnati; Detroit; Fort Lauderdale; Fort Myers, Florida; Las Vegas; Memphis; Minneapolis/St. Paul; Orlando; St. Augustine, Florida; St. Louis; Tampa

Many of the flights fly five to seven days weekly, but some run less frequently.

“The addition of Frontier to the Dulles family represents a significant, positive development for passengers interested in additional low cost, domestic travel options to and from the National Capital region,” Jack Potter, president and CEO, Metropolitan Washington Airports Authority, said in a statement.

Frontier is a Denver-based low-cost carrier that also offers service from Reagan National (DCA) in Arlington, Virginia, and Baltimore-Washington International Airport (BWI). The carrier said it will also add additional introductory fares as low as $39 each way following the sale through May 17.

However, news of the flash sale for the cheap flights inundated Frontier with web traffic, causing the website to load slowly or not at all.
