For more intense work, we have a CSV-formatted data dump of all our airports, countries, and regions, which we update every night. You can download these files and open them with almost any spreadsheet program or import them into your own database. You can even use them to set up your own, competing airport web site if you'd like! We'd love you to give us credit, like we give credit to our sources, but you're not required to.
