If BHD are considering building a hotel on the old ramp site, it would appear that they have lost the plot - with several established hotels within easy distance of the airport, this would really be a wasted effort.
It would seem Ferrovial are adopting the same attitude as Bombardier did when they controlled the facility - sit back and wait for airlines to approach them instead of aggressively pursuing new business - BFS have taken the latter approach and this seems to be paying off in terms of new routes etc.
BHD can't afford to sit back and rest on their laurels - unless some new airlines & routes come soon they really will have problems in maintaining their current level of growth.
