I shouldn't think MON will want to go to Circusair if they have an alternative.
They have a good relationship with Swissport at alot of Stations in UK and I would think (cash aside), they will stay put....
Then again maybe Circusair will undercut every contract renewal by a mil or so like they did in early 90's to get loads of non-profitable contracts (is that what 'Billy SMART' is all about?)
Let the dice rolling commence.............
