I don't want to spread any unfounded rumors, but you can see this for yourself. Lowestfare.com -- aka Carl Icahn's outlet for selling TWA's discounted Karabu tickets doesn't seem to be selling TWA tickets any more (other than STL O&D which aren't subject to Karabu anyway). Try it, any day, any city pair. There used to be tons of discounted TWA fares available. Now there are absolutely none. Any ideas why?
