BA: 'Let us decide if it's safe to fly'
And it has confirmed that European airlines have asked the EU and national governments for financial compensation for the prohibition on flying.
Later today I also expect BA to say that it believes - on the basis of the tests it conducted yesterday - that it is safe to resume at least some flying.
The airlines believe they have a moral case for compensation from taxpayers, in that they have been deprived of the ability to make their own judgements about whether it is safe to fly.
In effect, the European Commission - or rather the air-safety arm of it - has prohibited flights.
The airlines tell me that this is a break from the norm: they would typically assess, in consultation with regulators such as the Civil Aviation Authority, whether it's safe to fly.
This is what happened in the US, I am told, after the Montserrat eruption.
BA would like to be given back some responsibility for determining whether it is right to fly.
As for the prickly issue of compensation, the airlines believe there is a precedent: nine years ago, after 9/11, airlines were compensated for the four-day prohibition on transatlantic flights. BA received £22m from the British government under this scheme.
If compensation is paid this time, it would probably have to have an EU dimension, given that the flying ban is an EU decision.
