I've seen it stated in a couple of places (airport twitter account and media source) that Cork Airport handled 2.4m passengers last year. There are no official figures yet though.
That's a bit higher than the 2.38m-2.39m range that I was expecting. Now it may be that there has been rounding to two significant figures and that it is in that range. If it is actually that high, it suggests a very good November and December.
They are forecasting 2.6m in 2019 or 7% growth.
