CIRCLE WITH A DOT

Countries like China, India, US are huge... but maybe, there still aren't that many? We'd run out at 100 x 200 but of course, many countries have much fewer than 100 (Singapore has only 2).

How have we not run out of 3-letter IATA codes for airports? If it's 26 letters, there'd be only 17,576 codes. Are there really that few airports in the world?
