AI hub: Dublin Manchester or Brum?
If you consider the facilities BHX has to offer in two different forms, then it is clear where the bar to development and expansion lies.
Firstly for the passenger in terms of current infrastructure: terminal facilities, accessibility by road, rail or bus and its central local within the UK and proximity to ethnic strongholds are all very good, much better than most if not all other UK airports.
However, facilities for airlines wishing to develop routes and hubs are limited through the length of the runway.
This was, is and will remain the major stumbling block at BHX up and until the airport's management tackle the problem.
No extended runway, no major development. It is as simple as that.
