Aer Lingus will be running daily flights from Leeds to Belfast from autumn.
The airline will be operating up to three flights a day from Leeds Bradford Airport to Belfast City Airport from October 1.
Prices for a one-way ticket to the capital of Northern Ireland will start at £34.99, the Irish airline said today.
Aer Lingus, owned by Stobart Air, currently runs scheduled flights from Leeds to Dublin in the Republic of Ireland.
Stobart Air managing director Andy Jolly said: "As a result of the Covid-19 pandemic, Stobart Air has been challenged and we have worked hard over the past number of months to protect our airline and to position us for the future, once restrictions ease and passenger demand increases.
"Working with Belfast City Airport and Leeds Bradford Airport, along with our partners, Aer Lingus Regional we are pleased to establish a base at Belfast City to service flights to Leeds Bradford.
"High-frequency, day-return flights from Leeds Bradford to Belfast City Airport will cater for both business and leisure travellers for direct, convenient and cost-effective flights.
"We continuously strive to provide our passengers with frequent, convenient and affordable services. We look forward to welcoming our passengers on board this new route from Leeds Bradford from October 1."
Stobart Air will be resuming flights from Manchester Airport to Belfast on September 14.
