It is possible that TC will fold on Saturday - but if that was the case, we should be seeing unusual aircraft heading towards Gatwick as a minimum by now if a CAA smooth repatriation is to happen. With Monarch I remember there was a series of Qatar Airways aircraft flying almost in formation from Doha to the UK in advance of Monarch closing
If someone can see something on FR24, I'd be interested to know some aircraft registration details. Otherwise the possibilities are either TC continues to fly on Saturday (and possibly longer) or the repatriation is less smooth than the Govt and CAA might hope
