Ok, you here people saying Gatwick is at capacity, I guess they mean 'at capacity during peak hours'
I suppose they will have a descision to weigh up based on more prestigious airport (?) at Gatwick but at the back of the queue for slots and unfavourable flight times or potentially a competitive deal from MAG with their pick of the runway.
No doubt MAG would like to take them back from GIP at gatters. I wouldn't like to bet which way it will go to be honest.
