Never been to Ireland before. Flying on Aer Lingus (but with a BA flight number) in J Class, and I am AA EXP. The BA website gives me directions to the BA lounges in HKG and LHR, but nothing for DUB, and the EI website doesn't recognize my reservation number. Will I (and the wife, also in J) be able to access the EI lounge at DUB prior to our flight to LHR?
