Intro Aviation is to purchase Irish carrier CityJet today (March 31). The company announced last year that it was to buy the airline from its current owner, Air France KLM, for an undisclosed sum. CityJet will retain its codeshare with the French airline, but from today will operate using code ‘WX’. CityJet, which posted a €209m loss in 2012, will continue to serve Dublin, Paris and London City airports. The deal should be completed within four weeks.
