ALCOA, Tenn. — Allegiant announced a new nonstop route to Pittsburgh from Knoxville in a news release Tuesday morning.

The company is offering introductory fares as low as $49 to "celebrate" the new route, according to the release, which will operate twice-weekly, flying from McGhee Tyson Airport (TYS) to Pittsburgh International Airport (PTI). 

The new flights will start on May 17 and are expected to bring nearly 4,500 passengers to East Tennessee each year, the release said.

To get the deal, you'll need to book your flight by Wednesday, Feb. 13 and travel by Aug. 13. But, it won't be available for every flight, so you may have to do a bit of fare-searching on Allegiant's website.

With the new route, Allegiant customers can now fly to nine locations nonstop from Knoxville, Eddie Mannis, the chairman of the Metropolitan Knoxville Airport Authority, said in the release.

“We appreciate Allegiant’s investment in our community and will continue to work with them to grow their service in our region,” Mannis said.

Drew Wells, Allegiant's vice president of planning and revenue, also said in the release that the company is excited to grow in the area and bring more visitors to the Smoky Mountains.

“We’re confident that Pittsburgh-area travelers will take advantage of these convenient, ultra-low-cost, nonstop flights to enjoy the Great Smoky Mountains and all that this beautiful region has to offer,” Wells said.
