Smoking after terminal change T5->T3 LHR
Hi all!
I'm travelling to LAS in mid November and will arrive at T5 in LHR and due to the BA changes, this time I had to change to T3.
I know how to get out of T5 after arriving there to have a cigarette, but don't know if this works at T3 also.
When I take the bus to T3, is there a way to get to the border/customs to leave the building and an easy way to get back in?
Many thanks in advance!^
