I'm thinking the easiest way is to pull up the airport editor and right-click then select 'Print' from the menu. This will give you all the airport information listed on the airport editor. You can highlight only the airports table and print the selection, which would eliminate  all the menu stuff at the top of the page.

The other way would be to use the 'Map Utilities' to download the 'airports' file, then print that using notepad or some other text editor. - Mark
