Irish flag-carrier Aer Lingus has confirmed plans to switch its Belfast operations to City airport later this year.
Having spent five years at Belfast International the airline is to base two aircraft instead at City during the winter season, beginning 28 October, increasing to three next summer.
Aer Lingus chief Christoph Mueller says the change is a "commercial decision" which followed a tender process involving both airports.
It will focus on London Heathrow and London Gatwick with three daily flights to each, but broaden the network to Malaga and Faro in summer 2013.
"Northern Ireland's vital London connections are secure," Mueller insists. He adds that the carrier feels the switch will particularly appeal to business travellers.
"Business travellers based in the Belfast city centre will now be able to substantially reduce transit times from office to aircraft," he says.
"Jobs are secured in this move and indeed our plans for new routes, in the future, may see employment and investment increase."
