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.
CityJet chief executive Christine Ourmieres (inset) 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.
