Hey all. I haven't flown Continental in awhile (I moved from the Houston area to the Dallas area), but I'm about to fly Continental from IAH to DCA tomorrow. I printed out my boarding pass online, and my question is in the top left hand corner they have a sequence number. I don't think I've ever seen that before (or maybe just don't remember). What, by chance, does that number mean? I know it's probably irrelevant but I'm just curious. Thanks!
