Ryanair at it already. Everyone else canceling flights and they don't want to. Everyone else not wanting to take the risk but they have a different view.
Then why don't they take the risk and fly through it? Would it be because its easier to blame the 'authorities'?
There is now a clear policy on how to deal with the ash and its up to airlines to deal with it. All decided to cancel flights. Ryanair decide to cancel flights and blame someone else.
BTW, No sign of the second eruption thats due at Hekla although its been noisy over the past year.
