Hello,
This is my first time trying to fly aer lingus, and my first time using avios. I am trying to book 5 tix from PHL to DUB, but every date seems to only have 3 seats available. If I were to book those 3 seats is there any chance that they would open up more later? I also would like to transfer my points to BA and receive 30% then transfer them to Aer Lingus to book the tickets if that is possible, how long would that process take?
