Allegiant Air will end its service between Blue Grass Airport in Lexington and McCarran International Airport in Las Vegas on April 7, the company announced Friday.

Customers with reservations beyond that date will be contacted directly by Allegiant for a full refund.

Twin-engine Boeing 757 planes were used in the Lexington-to-Vegas flights, but Allegiant wants to deploy those aircraft in service to Hawaii, said airline spokeswoman Jessica Wheeler. The airline announced plans in July to begin flying to Hawaii by the summer of 2012.

"We've always been open and out-front that we bought the 757s for the explicit purpose of flying them to Hawaii," Wheeler said. "And now that flying to Hawaii is getting closer in our sights ... we need to pull that aircraft for flying to Hawaii."

Allegiant began service between Lexington and Las Vegas on Nov. 16. The airline will continue service from Lexington to the Florida cities Fort Lauderdale, Fort Myers, Orlando and Tampa.
