EasyJet is to restart flights to Spain, France, Turkey, and Poland from Belfast International airport in the middle of July.
The airline will add routes to Jersey and Croatia in August.
It resumed some domestic flights earlier this month, the BBC reports.
EasyJet said it will resume flying to almost three quarters of its route network by August.
Graham Keddie, managing director of Belfast International, said it was a welcome boost for the aviation industry and would help the local economy.
He added: “We have been working closely with easyJet and other airlines along with the Public Health Agency to ensure the safety and well-being of all who travel through the airport and have all necessary measures in place.
“We ask that everyone travelling via Belfast International adheres to the safety policies in place, including wearing face coverings and observing social distancing.”
