Through customs at Heathrow (T3), and get back out again?
As I have an 11hr wait at Heathrow coming up (landing in T3,leaving from T5, different tickets/airlines),and I am thinking about buying an extra ticket with Virgin Atlantic just to be able to pay to get access to their lounge. I understand that the Clubhouse lounge is airside? Will I be able to get out again, collect my baggage from a deposit box and go to T5 to take my BA flight?
And...will it be worth it? About 120 GP? I am considering some of the other lounges as well
