Yay! 3rd airport that I've identified today but having missed out on the other 2 chuffed I got this one.

That walkway and roof was very familiar, couldn't think where it was, was scouring my holiday photos from the last two years and as I was writing to ask whether it was a BA or OW destination it came to me.:-) Flew out of LCA on one of the last few flights served by BA's 767 before it was finally retired.
