I'm not in great rush. It's now 12:15 though as we're still being pulled so limited options now anyway.
Well I would advise when you land at LHR call BA and cancel your last leg on the basis that whatever you now have been rebooked on is several hours later than planned and of no use to you anymore - no need to explain the whole plan of going to DUB and coming back on a separate ticket. They will cancel the last leg and note on the booking it is due to IRROPS - you may get a few pounds back for the last leg for taxes and fees. You can then finish your journey at LHR.
