bmi is right to hold a grievance with EMA if it is true that Go have been given financial incentives to base at the airport. BM has been at the airport since it's beginning and has been an instrumental and crucual part of it's success. This does not mean that they should get special treatment but they at least deserve to be on a level playing field! Shame on you EMA if you have offered such incentives to Go.
On the positive side, good luck to Go ... lets hope EMA can accomodate both airlines.
