Flybe has expressed its disappointment at the European Commission's decision to block Ryanair's proposed takeover of Aer Lingus.
The Exeter-based airline had been lined up to take over some of Aer Lingus' short-haul routes in a move aimed at overcoming competition concerns had the deal gone ahead.
In a statement to the stock exchange, the company said: "Flybe is disappointed by the Commission's announcement and remains firmly of the view that the proposed remedy – whereby Ryanair would transfer a number of aircraft and operating routes to Flybe – would have afforded credible and robust competition, including new jobs and bases in Ireland."
A package of concessions submitted by the Irish budget airline in an effort to overcome competition concerns included breaking up Aer Lingus, with 43 routes and at least nine aircraft and crew transferring to a new Flybe Ireland division of the Exeter-based group.
The deal was conditional on Ryanair's acquisition of Aer Lingus going ahead.
Ryanair has reiterated its intention to appeal against the European Commission ruling.
