I was looking at taking EI 131 from DUB to BDL, figured I could earn AS miles on this route, but when going to booking, it shows " EI 131 DUB - Terminal 2 A S L Airlines Irl For Aer Lingus Boeing 757". This is strange, since it's marketed by Aer Lingus, the metal is Aer Lingus, yet there is another airline running the show? It's an EI flight number, so many AS would credit miles. Anyone have any idea?
