You just have to look at the threads on here, compare TCX, BACF and Cityjet to the Aer Lingus one which is 17 pages before anyone has even been to Dublin.
They will I reckon get more than enough who meet the standard, they might not be quite as good as the successful Aer Lingus candidates but the airline would be able to argue that at the latter stages it's very close and quality is largely subjective.
Shame it's not on ability though.
