The carrier will be adding up to 10 narrow body jets to its fleet in phases, serving the domestic, Asean and Asia Pacific markets out of Penang International Airport.
"Based on available forecasts, domestic and short haul travel will be most preferred in the current environment, hence it makes commercial sense for Firefly to supply this demand but from the northern region," said Malaysia Aviation Group (MAG) chief executive officer Captain Izham Ismail.
Firefly will be complementing sister company Malaysia Airlines in serving the leisure market while diversifying its base connecting secondary cities in Malaysia to Sabah and Sarawak, Thailand, Indonesia and Singapore.
MAG, in statement, added that there's the possibility of Firefly deploying Boeing 737-800 aircraft from Malaysia Airlines.
Firefly chief executive officer Philip See said the operations at Subang Skypark will still continue.
"We see strong potential in this dual hub strategy, while maintaining our turbo propeller service out of Subang Skypark, serving the mix of corporate and leisure travellers," he said.
With the new jet operations, Firefly will offer a flexible service concept, with product unbundling to suit price-sensitive passengers.
Passengers will continue to enjoy the complimentary 20kg checked baggage allowance and redeem Enrich loyalty points.
