There was an article today where a Welsh family had the same issue.
A hotel / apartment manager came into the room in the middle of the night and confiscated the passport for ransom of approx £400. The police were called and issue resolved.
The main issue is that the hotels / apartments do not understand the compensation procedure. The CAA has provided an overseas contact number for hotels/apartments with Goldtrail customers to receive more information on their compensation package.
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.
