Well, if AirPro really signed the ground handling contract with Britannia Nordic, I suppose they offered those services almost for free... They REALLY need new customers, as the handling of only a few FlyMe and Karthago Airlines flight can't be too good business. Therefore, I believe that working conditions and salary of employees is not amazing.
There are too many ground handling companies at Helsinki... My best guess is that either AirPro or InterHandling will not survive.
