I don't work for Jet2, but I do hold shares in them. From what I've read in their financial report, they seem to be well placed to weather this fiasco. They own a lot of their own aeroplanes, with no lease costs, and as far as I know have a large number of seasonal (cabin) crew. I wouldn't say that they have "massive overhead costs", certainly not compared to easyJet or IAG.
