Rumour has it, portakabins will be set up for crews somewhere over near the Monarch hangar and they will be bussed to the aircraft. The main offices though will be at the train station building... just what I've heard.
I believe Monarch weren't too happy about the possibility of them being on a remote stand a lot of the time. However, they, like a lot of other airlines at the moment, are looking to lower their cost base and so I do wonder if MAG offered some kind of financial incentives in whatever deal was struck.
