" There is a better chance that Wizzair goes bust first"
You seem to have some difficulty to accept, that by all normal parameters, Sky is already bust, they are merely concealing it by A - extending their loans repeatedly. & B - Deferring release of their results repeatedly.
I don't dispute that this may well continue for some time, but by any reasonable assessment they ARE already bust. If not, how come so many aircraft were repossessed by the leasing companies ? couldn't pay the bills no ?
Sounds like a reasonable definition of bust to me, can't pay bills, leased assets removed by owner, Oh, and employees paid late repeatedly, and probably not fully.
