Belfast City Airport is to upgrade its departure lounge and central security area as part of a major £15m investment.
The George Best City Airport will also increase its retail space by more than 30% and its food and beverage facilities by 25%, to give customers a broader choice.
The investment will also include the purchase of a new fleet of airport fire appliances.
Chief Executive Brian Ambrose said: “The strategic designs help future-proof the airport and we look forward to continuing what has been a successful period across many areas of our business.”
The upgrade is expected to be completed by October of this year.
