From what i'v heard the pilots were screwed over royally and are owed wages from september and october also owed is redundancy notice period pay, accrued leave, expenses, per diems, flight pay etc.
Money owed ranges from £11,000 up to around £20,000 for the captains. That is per pilot of course! I believe the pilots have taken legal action against Viking, Viking Hellas and the CEO of Viking. This is most likely the REAL reason Viking Hellas has changed its name to 'fly Hellas'.
