Banotok,
I personally feel the airport may of taken the view that they are happy with the results from operating as an airport. Afterall it is a business they are running. Whilst I accept the lack of destinations and carriers offered at present and I am not airport management, but if it was losing money and really really needed carriers then I am sure they would invest in giving away free fees to a Ryanair or Easy in return for a few hundred thousand pax a year that the low cost carriers can give. These pax spend money in the terminal shops - parking etc.... and its these shops that pay the famous high rent and 6% of its turnover licence fee to the airport! It is a known fact BHX probably like many airports make more in "other" charges than in landing fee´s.
Regds...........
