Frontier Airlines is expanding service just in time for the summer travel rush. The low-cost airline is adding nonstop flights from a dozen new cities including Savannah, Chicago and Seattle starting in June and July. To celebrate, Frontier is offering flights starting at just $19.

　　To snag these deals, book by 11:59pm ET on April 10 for travel from June 5 through August 31. Blackout dates include July 1, July 4 to 8, July 11 to 15, July 18 to 22 and July 25 to 29.

　　New service includes flights between Buffalo and Philadelphia, Denver and Savannah, Dallas and Seattle and Chicago and Salt Lake City among several other routes.

　　As consumers look to take to the skies this summer for leisure or business travel, were thrilled to further expand our route map from coast to coast, said Josh Flyr, the vice president of network and operations design at Frontier Airlines, in a statement. More destinations from more airports means Frontier Airlines can provide Low Fares Done Right to even more customers during the busy summer travel season.
