Budget airline Jet2.com has said it is dropping its Belfast to Barcelona route, but is adding Croatia and Cornwall to its destinations.
The airline, which flies from Belfast International, said routes to Dubrovnik and Newquay would create about 50 jobs.
It said it was ending the Barcelona service from 26 October due to competition on the route.
Jet2.com said customers who have booked flights to Barcelona in 2009 would get refunds or a free destination change.
Jet2.com boss Philip Meeson said they were committed to operating out of Northern Ireland.
“These are exciting times for us and, unlike other airlines which are grounding planes due to hard times, we are expanding our range of destinations and are planning to increase our overall capacity from Northern Ireland,” he said.
