Good grief. The 'design' of this airport goes from bad to worse. Skimpy bus shelters made from unsuitable material which is impossible to keep clean. Narrow shelters which will lead to passengers huddled beneath blocking movement of travellers in front of the terminal. No cover for passengers loading and unloading at the side of the coach. Narrow bus shelters giving little protection from the horizontal rain which frequently presents itself on this exposed site.
A large, self cleaning glass roof supported by cantilever structure is what's required with sufficient overhang to allow boarding to be completed in the dry, while the rear of the bus is open to ensure diesel fumes are ventilated.
I'm not talking the size of St Pancras but something along the lines of Farringdon station.
