BFS bridges
There were four bridges at one point, 14/15A, 18, 22/23 and 27. As mentioned BA and BD had their own for their LHR services.
Old 22 bridge was originally half way down the international pier when the stands were slightly different (approx pre-1997)
It was then moved to where the glass air bridge is now and it could rotate between the present stand 22 and the old 23 which was at a right angle to 22 (14 bridge could also be used on 15A and maybe the old 13).
The bridge on 27 was a nose loader ( could only move up/down and back/forward)
It was originally the bridge at stand 18 used for BMI but was moved to 27 when a new bridge was placed on 18 (the more flexible jetty type). It was removed when stand 28 and 29 were created.
A real shame that there is only one bridge these days as they do present the image of more successful airport! But thats the nature of BFS these days!
Perhaps a small sacrifice for the much more extensive network the airport has these days.
