Thank you both for the reply.


The flight is booked as EI all the way through. I have business class on all flights. However when I look at my ticket the short flight is billed as I/AerSpace Class ( not sure what that means)
While I booked the flight with Aer Lingus..... the first leg ( LHR - Dub) is operated by BA.

I am part of BA Executive Club but I do not have status of meaning with them yet.

I know i could get terminal 2 access to Aer Lingus lounge but since my flight is leaving out of T5 that is why I ask. I prefer to be in the same location as my flight out if possible.
