Frontier Airlines is continuing to scale back its presence at Pittsburgh International Airport.

The Pittsburgh Post-Gazette reports that Frontier has opted to drop its daily flight to Las Vegas from the Pittsburgh International by Oct. 4. Frontier's decision comes after the airline ended flights to Chicago and Atlanta last year.

The Denver-based airline will keep seasonal flights to Denver and Orlando.

Frontier Airlines announced it will end its service from Pittsburgh to Denver just one month after it started offering the flight.

Officials from Frontier Airlines and the Pittsburgh International Airport said the airline would discontinue flights to Denver in January on a seasonal basis, although the flights were not billed as seasonal when they began in June.
