gate 22, When MOL agreed to Launch flights from BHD he had been promised that the runway would be extended and he has said this publicly that the runway 'will be extended'. Rest assured that the issue of number of flights per year is a red herring and this too in time will be 'adjusted'.
Sammy Wilson has avoided meeting the locals near the city airport and he has the final say and that says to me that he is planning to grant the extention. Commerical reasons will dictate.
But it is a good question that you ask. Me thinks that this has all been mapped out and planned and is only a matter of time before the increases come and the planning agreement is altered. I read that last year the numbers (limits) were far exceeded.
