Ryanair and Aer Lingus engage in Twitter war

The rivalry between Irish airlines Aer Lingus and Ryanair has now spilled onto social media.

Never a pair to resist a dig at each other - the airlines took to Twitter to trade shots this evening.

Having been the target of several Ryanair takeover bids, Aer Lingus got the ball rolling by claiming the aircraft featured on the revamped Ryanair website was in fact an older Aer Lingus plane.
