Ryanair offers to give up 46 Aer Lingus short haul routes Under the latest proposals, Ryanair would surrender 43 short-haul routes to Flybe, while BA-owner International Airlines Group would take Aer Lingus's routes between Ireland and Heathrow, according to Bloomberg. Aer Lingus shares have soared since the turn of the year and closed on Tuesday at €1.22, just 8 cents off Ryanair's offer price. The EC has until February 27 to deliver its judgment on the proposed deal. Ryanair, Flybe and IAG declined to comment.
