From FlyerGuide Wiki
We opened up JDiver's outstanding post for everyone to add to here on the wiki.
There is a FlyerTalk Glossary of Terms commonly or even occasionally encountered on FlyerTalk. (A very few are listed below.) N.B. We try to avoid abbreviations in thread titles, because Search can not deal with three - or fewer - characters.
There is also a FlyerTalk Airport Code Lookup feature.
