Should somebody update the wiki at the beginning of this thread? (I could help.) It lists airlines that don't exist anymore, doesn't list airlines that are now OW carriers, and contains a number of factual errors (i.e. it says if yours is a D ticket and there's no business class on a flight, you get downgraded to L, whereas in reality you get downgraded to B, which makes a difference). There are also a few obsolete links in the wiki.
