Service Standards
In relation to how MAG keep an eye on service levels, there were plans or there is in place a Ground Handling Licence. This is suppost to keep a check on the handling agents to ensure they perform to the correct standards and stop the airport suffering from lack of service from a service provider where they have no control over.
I'm sure this was in place but i may be wrong...things at MAG take forever.
Many service providers would love to work together but many facilities are held back or stopped all together by MAG.
