Blue lost a shed load of cash the last time they operated to ACI so doubt a return would be in the offing.
With an Open Skies policy in JER & GCI there is no need for anyone to buy the airline, should it fold any interested party can just step in on a route should they so wish.
Coates has had his three or four hotels on the market for some time now (2 years or so) so if the rumour is true I would guess that they, along with the airline would all close at the same time, as we know he's not in the best of health so it would seem to me he's getting his affairs sorted.
I wonder if all the a/c leases run out at the same time...?
