As someone rostered to operate 4 sectors this afternoon, I've been trying to gather as much updated info as I can. Having just been on to the CAA website, I'm interested in the CAA requirements that airlines are to perform "an intensive maintenance ash damage inspection before and after each flight". I expect to have company guidance on this later today, but it isn't immediately clear to me which airspace this applies to, given that there still appears to be areas with low concentration of ash over some parts of the UK today and that the areas affected are constantly changing. Glad to be back flying, but haven't seen much discussion of this inspection requirement.
