On R4 this morning it was suggested that it would cost the CAA £600 million to repatriate everyone. No idea whether that is accurate, or a wild guess.
Seems a bit overkill. the whole Monarch operation was £60m for 110k pax
TCX have potentially 180k, so for flight only, £100m would make sense.
The other £500m could be due to people who have booked holidays and getting refunds through ATOL, but why the government has to pay this, when the ATOL system is seperate, i do not know
