How this directory is organised
The directory has four ways in. The countries directory groups airports and airlines by country, one page per nation. The US states directory does the same thing for travel inside the United States and puts every airport under its nearest state. The airports browser is a flat A to Z listing of every IATA-coded airport, useful when you already have the three-letter code in hand. The airlines browser covers the carriers, and the routes section ranks city pairs by how heavily they're served.
An airport page gives you the carriers operating there, the destinations they serve, and a route table that jumps straight through to each destination's own page. An airline page lists a sample of the routes filed under that carrier's code. Every link points to a real, fully rendered page, so you won't hit a dead end.
