Went through BGY last year on a last minute re-route. Expected the usual tired loco terminal but was pleasantly surprised. Bright and airy once airside.
BFS needs redevelopment - not just superficial rearrangement of restaurants but proper re-development. At certain times of day it is running at near full capacity in terms of stand usage so there is little point investing in the terminal unless they are also prepared to upgauge everything else: stands, parking, transport links etc. This only make sense if the owners think there is headroom to grow. Otherwise it makes more sense for them to squeeze the asset until it becomes more expensive to maintain the old buildings than to build a new one. It is the shabbiest looking medium sized passenger airport in the UK with maybe the exception of Exeter.
