I am sure they know what is best for the company.
1, you can’t travel unless essential and when will that end ?
current figures are worse than March/April last year to Jet2 are looking forward and comparing and have decided that it is unlikely to get the go ahead before end of March and that’s what the government were hinting at yesterday.
2, all the flights and holidays will mostly be running at a loss so better to ground everything instead
3 I bet nobody is booking any flights or holidays to depart before March now until the ban is lifted.
I expect the other operators to follow
