It appears that the [[final?) numbers for 2019 have been released.

Overall, an increase of 1.5 million passengers [[+4.3 %).
The official number for 2019 appears to be 36,769,279, quite a bit better than my rough estimate. That's an increase of 17.3 % since 2019.
For December 2019, the final number appears to be 3,254,770 [[-0.3 %) for international travel. Slightly better than my estimate.
Overall, seems like a pretty healthy increase, all factors considered. I imagine it'll probably make a minor local headline or two this week.
