Spirit Airlines has moved up the start date for its 2013 seasonal service between Niagara Falls International Airport and Myrtle Beach, S.C., and will bolster its service to Fort Lauderdale, Fla.

Two weekly nonstop flights between Niagara Falls-Myrtle Beach service will begin Feb. 15, nearly two months earlier than in the previous two years. Its service will increase to four weekly flights on April 25.

Spirit is moving up the start date for service to Myrtle Beach at a total of five airports in its system.

Additionally, from Jan. 14 to April 25, Spirit will operate daily service between Niagara Falls and Fort Lauderdale, instead of three days a week, Spirit said.
