During the press conference Aviator was presented as the Ryanairs handling agent at CPH.
It won't be Aviator doing the handling, rather their 'lower cost' CFS (Copenhagen Flight Service) offering. The workforce in CFS is, however, in the exact same union as everyone else working on the ramp in CPH.
Why Aviator sprung for Ryanair is pretty simple: They will lose their biggest customer (Norwegian) on the 1st of April, representing around 50% of their revenue, to Menzies Aviation.
But, just to be clear, even if RYR has signed a ground handling agreement, the handling staff still won't touch a RYR aircraft unless they sign a collective agreement for their cockpit and cabin staff. Which they've said very clearly that they won't.
