I purchased a child's Oyster Photocard and arranged to pick it up upon arrival at Heathrow 123 Underground station since I was planning to arrive at T3. Well, the airline "adjusted" my flights so now I arrive at T5. How far away is the LHR 123 underground station from T5, and what is the best way to get there? Thanks in advance for any advice. Dan
I did a little research on the LHR website and think I answered my own question. It looks like the Heathrow Express train is free and connects T5 & T123.
Free for the child, not for you, I presume?
Heathrow Express is a free ride for everyone between terminal 5 and the rest of the airport.
The underground is also free for transfer between terminals at LHR, although this doesn't help the OP as you still need an Oyster card to access.
