One thing I'd say about BHD,is when the new terminal was built it was pretty nifty.Though with the increasing traffic using it I feel though the design itself sucks to be quite frank....as to me they haven't given themselves a bigger terminal in which any further expansion could have ocurred.Now they will need to do some major building to do this.
Though talk of re-opening the old terminal,building a hotel round the Sydenham by-pass area still continue to echo the airport.
