(Springfield, Mo. Feb. 17, 2005) — What happens in Vegas, may stay in Vegas, but it will soon start in Springfield, Mo. as Allegiant Air, LLC, today announced new nonstop jet service to Las Vegas. The Las Vegas-based, low-fare airline today announced that the company will inaugurate scheduled service from the Springfield-Branson Regional Airport to McCarran International Airport (Las Vegas) beginning April 21, 2005. To kick off the new service, Allegiant is offering introductory fares as low as $49* one-way on flights from Springfield to Las Vegas.

“We are extremely pleased to extend the Allegiant brand of low-fare, nonstop jet service to the people of the Springfield community,” Maurice J. Gallagher, Allegiant Air president & CEO, said. “This is an exciting new addition for our airline and our customers as we launch the only scheduled nonstop service between the Queen City and Las Vegas.”

The new flights will operate twice weekly, with service Thursday and Sunday. Beginning April 21, flights will depart Springfield at 8:35 p.m. arriving in Las Vegas at 9:40 p.m. Flights leaving Las Vegas will depart at 3:10 p.m. arriving in Springfield at 7:55 p.m. (all flight times are local).

“This is an exciting development for our community and our airport,” William Kirkman, chairman of the Airport Board, remarked. “Allegiant service to Las Vegas marks a first for Springfield with non-stop service to one of our most popular leisure destinations. I’m confident it will be a great success and we welcome Allegiant to the community.”

The carrier will utilize a full-size, 150-seat MD-80 jet aircraft on the route. The airline said that its market research and input from local community leaders indicate that the Springfield area will welcome the new nonstop flights and low fares to Las Vegas as an alternative to connecting flights or long drives to other airports.
