I don't work for Aer Lingus myself, but have some contacts who do. As I hear it your seniority and allied entitlements have been preserved and you will be offered employment before anyone else. When that might happen is another matter. Your position is a lot better than you might think from some of the comments above (notkahouse being a prime example). IMHO you would do a lot better to ask IALPA for the specifics than to post here.
