EI to BA transfer at LHR

Santa Claus

Most of the times I go through heathrow I get BA from DUB and so I arrive and depart from T5 hence minimal connection fuss.
Last time I connected from an EI flight was years ago when they were still in T1 at Heathrow and you had to get a seat down the back of the plane to disembark via the rear door for the bus to the connections centre.

Anyway, can anyone tell me what the procedure is at LHR t2 arriving on EI and transferring to T5 (all on BA booking so everything checked through at DUB)....don't want to get a seat up the front of the EI flight only to find I've to make my way to the back to take the stairs to the bus.

Thanks

Easy

Exit front door of aircraft, follow the signs to connections, go DOWN the stairs, get a bus to T5

At T5, up the stairs to flight connections
3 queue's you want so stay in the right side of the corridor to avoid the passport queue
Have your passport and boarding card to hand for the conformance check

Make sure you check in online with BA for the LHR flight so you have a boarding card before you get to LHR (EI will probably reissue it)
