Looking at the revised schedule published on the CAA website it seems that SAGA airlines and Viking are no longer prepared to operate the repatriation flights from Turkey and seem to be mostly replaced by Onur Air. The same applies to Greece where Monarch, Jet2 and Thomas Cook are operating some repatriation flights.
Jet2 to EMA is using spare capacity on the flight for Goldtrail passengers. It is not an additional flight.
