Dublin-based airlines CityJet and Stobart Air have signed a partnership agreement that will see Stobart operate CityJet's Cardiff-Edinburgh and Cardiff-Paris routes.
CityJet was acquired earlier this year by Germany's Intro Aviation from Air France-KLM.
Stobart Air, formerly Aer Arann, already operates the Aer Lingus Regional service under a franchise agreement, and also works with FlyBe. CityJet chief executive Christine Ourmieres said she looks forward to developing the airline's offering with Stobart Air in the future.
"Adding CityJet to our partner portfolio is a further positive development for Stobart Air," said Stobart Air chairman Sean Brogan.
Stobart Air has also just secured a taxpayer-backed public service obligation contract to operate air services between Dublin and Donegal, and Dublin and Kerry.
