Yeah, he mentions that: "There are in fact airports on Antarctica, but they are not classed as medium or large, and do not have scheduled services according to this dataset."

The list of airports in Antarctica is surprising long, but most of them are ice or snow and probably need to be remade each year. Some are hard to impossible to see on google maps, but many are quite visible.
