I actually tend to think that if any company is going to come out of this well it'll be Jet2. People will be going on their two week summer holiday when this is over, whether it be this year or next. I'd not be surprised to see a busy winter 20/21 too for them and TUI. I'd expect business and city break type travel to suffer more than bucket and spade flying, and as I understand it Jet2 have a very loyal customer base and seem to major on customer service. I've no doubt that if it were permitted, Brits would still be travelling abroad now. It's in the psyche.
I don't know enough about the company to judge what will happen to the Airbuses. I do think it's only a matter of time before Jet2 joins the rest of the industry in enforcing paycuts/ unpaid leave. That seems inevitable.
