I think you’re chasing your tail on this one.
Capital projects like this frustratingly take time to follow due process, even in the slickest of private or publicly listed firms, never mind a semi-state with public funding. I think the 12 month turnaround is amazing when you understand how things work, state involvement slows everything down too.
As an example of how public versus private timelines differ, look at how prolonged the public job hiring process is:

Most private companies are now working to a plan that involves a screening interview, and then a follow combined tech/management interview.
I would rather a 10 week stint that knocks out the whole job, than a prolonged drawn out series of disruptions. From what has been written recently the airfield is antiquated, looks like it’s more than a re-tarring job.
Better to close it during off peak than over Christmas, it simply wasn’t possible to bring it forward any sooner.
It’s not like those coming home don’t have temporary alternative routes. Dublin airport is 2hr40 up the road.
