LHR Centurion Lounge access when connecting
I used the Centurion lounge on my way in to Europe, where I landed on terminal 5 and transferred to terminal 3 for a connection to mainland Europe. Now I am going to be flying back in reverse (connecting from T3 to T5), but it is not clear to me if I will be able to use the lounge before transferring terminals (seems you go direct from plane to bus without real access to terminal). Is that correct? If yes, which PP lounge is better in T5?
