Not sure that lack of CC was the reason for all the Sub Charters yesterday as it was the end of the Summer season there was always going to be a number of ferry flights so it made sense to use some ad hoc carriers based in mainland Europe to cover some of the the flights with the Belgian OO-MAX operating a revenue flight out to Tenerife for Tui Belgium as start of their winter programme then operated the last of the Tui summer flights back to EMA.
I am told it was also complicated more by Red tape ,due to some crew being on a contract only until 31/10 that created issues with liability insurance when the flight arrived back in the UK past Midnight.
Jet2 did it in a slightly different way with doing a few double drops in the UK and Greek Islands along with aircraft swaps down route
