Aer Lingus do hire people of other nationalities however it is to be expected that those successful will most likely be Irish. This isn't due to discrimination however, having met many cadets from the bafpp I also find they consist mostly of British people. The reason for this is an Irish person is more likely to stay with Aer Lingus for their entire careers, they don't want British people getting the hours then running off to BA or spanish people running off to Iberia etc. An Irish person is also more likely to mean it when they say they have always wanted to fly for aer lingus because it is their national carrier. Having someone from germany saying they have always wanted to fly for aer lingus and they've never even lived in dublin but suddenly want to move their life to ireland is questionable ! I doubt I would be hired for any national carrier for similar reasons anywhere outside the UK and Ireland.
