I checked BA's flight info page for flights to/from IAD and DUB from LHR. All that it shows is terminal 5. Not much help. I tried 3rd party sites like flightaware and flightstats. No luck.
I want to know what kind of transfer I will need to do for IAD-LHR-DUB flight next month. Is it T5A-T5B or any other combinations thereof. I'm used to the actual gate info on AA.COM for its flight info.
