The Airport management need to realise that they exist to serve the airlines and their passengers. My experience of the previous regimes in charge at MME (going back almost 30 years) has been that they tend to try and dictate to the airlines how they should run their operation,this constant amateur meddling usually ends up with the airline getting tired of the hassle and pulling out.
MME needs to draw in business and if that means making a short term loss to rebuild its customer base then surely it makes sense rather than the current approach of trying to screw potential operators with high charges and passengers with stupid departure fees.
Try employing some security staff with customer friendly attitudes rather than the petty jobsworth dictators that infest the place normally
Try offering free car parking rather than trying to wring as much as possible out of passengers
MME needs fresh thinking. business minded. professional. airline friendly management to get it out of its current, possibly terminal (no pun intended) decline. It could be a great little airport and it deserves to survive and prosper but it needs the quality leadership that has been lacking for a long time
