Ryanair is to run more winter flights from the City of Derry airport.
A service to Birmingham relaunched in the summer is being extended into the winter season.
An extra return flight to Manchester will see the no-frills carrier operate six returns a week operating on Mondays, Fridays and Sundays.
The additional capacity came as Ryanair said it has carried five million passengers through the Northern Ireland airport since starting services 24 years ago.
Airport managing director Steve Frazer said: “Passengers will benefit from a new Ryanair Birmingham service on a Monday, in addition to the existing Saturday service.
“This will be ideal for business travellers departing at the start of the week and returning at the weekend, as well as students who regularly commute, whilst offering leisure passengers a convenient weekend break.
“Ryanair’s Manchester will continue to operate on a Monday, Friday and Sunday, again ideal for both business and leisure travel, with additional services available across the Christmas holiday period to meet the needs of our local catchment area.”
An airline spokesperson said: “This year, Ryanair’s City of Derry airport traffic will grow 66%, demonstrating Ryanair’s long-term commitment to boost Northern Ireland’s air traffic, tourism, jobs, and economy.”
