Tom -> There are still a depressingly large number of issues when it comes to aviation infrastructure in Ireland. However, Dublin getting a second, longer runway is probably the number 1 that needs to be addressed. After that, an extension to Cork's existing runway, with parallel taxiways and more apron space is probably next. While both airports have had welcome new terminals, the airfield facilities have not kept pace. Unfortunately, for as long as we treat aviation as something where a minister can announce a small upgrade for the local airport and buy a few votes as opposed to something where we have a national strategy, that will always be the way.
Seljuk22 -> Considering the number of flights cancelled because of volcanic ash, that doesn't sound the worst. Maybe a drop of just under 10% if we factor that out.
