I was wondering if anyone could explain anything about the underground tube, heathrow terminal 5 ?
Is it actually located inside the terminal 5? I have a day away in Germany tomorrow coming back Saturday, but from there im in London, so will leave the car at the airport.I would be getting the underground back on sunday, So what i was wondering is, is it ok to enter terminal 5 underground station and leave Heathrow terminal 5 without have an flight or anything at the airport, and get back to the carpark. Basically using it like a commuter,
Thanks in advance
