This is probably the most frequently asked question! The data is from here: http://ourairports.com/data/

I had to limit the number of airports displayed for performance reasons. I filtered the airport data so that only those airports with scheduled services and which are denoted "large" or "medium" are included (according to OurAirports), bringing the number down to 2,980.

Suppose that'll explain why there are at least three airports included in Ireland that have no scheduled services at all: the data's from nearly a decade ago

I am amused how airports like Lands End (which was grass runways only before 2014), and Chester(!!) made the cut. Plymouth closed in 2011

However that's all nitpicking, this is a pretty cool map, I'd never encountered Voronoi diagrams before.

Interesting. The data is from 2014, which is when I created the visualisation. Perhaps I should auto-update it every so often!

Most recent item on "recent changes" was five years old in 2014. Galway Airport's certainly been shut for a lot longer than that.

St Helena airport is open and technically operational. It's certainly one of the most remote airports on the planet (this happened post 2015)

It would be nice if there was a slider for N. I like to think my computer is recent, but evidently it is not!
