Belfast City Airport is set to grow its European city break business with the new arrival of a Spanish budget airline.
Low-cost service Vueling is adding a twice-weekly service to Barcelona.
The new route to the city's El Prat airport will begin in May next year.
Vueling is part of Irish businessman Willie Walsh's International Airlines Group (IAG) - which also owns British Airways.
Belfast City Airport boss Brian Ambrose welcomed the newest arrival.
"It remains our aim to attract new airlines to Northern Ireland and facilitate more direct European routes from Belfast," he said.
"We are therefore delighted that Vueling has chosen to include Belfast City Airport as one of a select few UK airports in its plans to expand its network."
Vueling - which has been running for 10 years - boasts a network of around 100 destinations across Europe.
It's currently undergoing a major expansion of routes and services.
Niall Gibbons of Tourism Ireland said the announcement was "good news for tourism to Northern Ireland".
