Aer Lingus Regional, operated by Stobart Air, will add a Glasgow service to its network from George Best Belfast City Airport this summer.
The new daily route will operate from July 1, with 11 flights a week, and will increase to 19 flights weekly in August.
It brings the total number of destinations served by Aer Lingus and Aer Lingus Regional from Belfast City Airport to 10.
Katy Best, commercial director at Belfast City, said: “With up to 19 flights per week, the convenient flight schedule will no doubt appeal to both business travellers who can book a same-day return, and those seeking to reunite with friends and family or take a short break this summer.”
Andy Jolly, managing director at Stobart Air, which will operate the flights, added: “Stobart Air has called on the UK government and the Northern Ireland Executive to support the industry and work with all industry stakeholders on a plan and timeline for the resumption of safe air travel.
“In light of the successful Covid-19 vaccination rollout allowing air travel to increase safely, we are pleased to add this new route from Glasgow to Belfast to our route network, which will cater to both business and leisure travellers with direct, convenient, and cost-effective flights.”
Aer Lingus Regional already flies to Birmingham, East Midlands, Edinburgh, Exeter, Leeds Bradford, and Manchester from Belfast City Airport, and recently announced new services to Cardiff and Newquay will start on June 28.
