Emerald Airlines, which operates the Aer Lingus Regional services, is expanding its routes from Belfast City Airport, with new routes to Glasgow and Exeter.
The airline already services Birmingham, Edinburgh, Leeds Bradford, and Manchester from Belfast City Airport.
Emerald Airlines is also adding two aircraft to its Belfast fleet, increasing the frequency of its existing services to Manchester and Birmingham, which now operate up to three times a day.
Ciarán Smith, Head of Commercial at Emerald Airlines, said the airline was extremely pleased with the feedback it had received since beginning its operations from Belfast City Airport.
"Striving to be the airline of choice to and from Belfast, we are now adding to our fleet with the addition of two more aircraft. This allows us to increase the frequency of our flights in line with consumer demand, providing more options for those travelling to and from Belfast," Mr Smith said.
Ellie McGimpsey, Aviation Development Manager at Belfast City Airport, said the airport was seeing strong demand for flights to England and Scotland, with customers visiting family and friends, making the most of a long weekend, and getting back to business travel.
"The Aer Lingus Regional routes have been very popular with both inbound and outbound passengers, and we look forward to working together to further develop the network from Belfast City Airport," she added.
