The next person to start a Bump Thread should ask mtparadis for the odds. He always seems to have a "wise" comment on bumping. Telling from his reactions, He probably has had some really bad luck trying to snag a bump.
It is very hard to tell if you will get a bump now that they have journey control. Just because they are selling 6 seats doesn't mean squat anymore. You would need an insider to check the loads. I wouldn't count on a bump unless a previous flight is cancelled or the flight is zeroed out.
Best of Luck!
