I'm looking for a flight for self, wife and son for Sunday Aug 4 to DUB, ideally for mid-day so we can get to the DUB Conrad early enough to enjoy to the hotel (only 1 nt booked there). I'd like to get lounge access where I can order him the famous pub burger. What are the best options for this? I'm OWE thru AA and also BA Gold.

Looks like there is only 1 flight out of LGW a day and not until evening. And nothing out of LCY at all. BA has a gap in flights from like 1000 to 1500 from LHR, which is odd? Does EI fly out of LGW at all? If we flew EI out of LHR would we even have lounge access or would we be stuck in the wrong terminal? I assume all the BA flights are T5, or are there any to DUB out of T3?
