Something interesting happened to me today: had a two hours connection coming in from ARN and leaving to BOS. The usual plan was to cross the UK broader and enter GF through the First Wing. But then the ARN flight ended up parking in T5B and my connecting flight was already showing as B Gates so breezed through T5B-T5B(C) security (which was literals empty) and walked to GF in no time, thanks to the passageway (which seemed under construction BTW).

Brilliant
