From the CSO, these are exact figures for international passengers. so all that is excluded is the very tiny number of domestic passengers in Shannon
2016 (Jan-Oct): 1451018
2017 (Jan-Oct): 1381549
2016 (Full Year): 1653514
2016 (Nov-Dec): 202496
We also have a figure for total passengers at Shannon for 2016, which shows 1,674,567, with the implication that the total domestic figure is 21,053. I'm surprised it's that high, but it's still only a fraction
It would take over 35% growth in November and December to get to 0.1% growth for the year. I just can't see that.
