similar question
I am arriving from JFK with BA in LHR and have a connecting flight to Hamburg (HAM), also with BA but some 4 hours later. I will fly (thank god) business class. Any tips where to spend my 4 hours, i.e. which lounge? I haven't been in LHR for some years now, all I remember is that I have to switch terminals and go through the flight connection center (and passport controll obviously).
Any help appreciated.
Thx
