I am a true novice here. Can someone please tell me how to check the load on a particular flight? I have searched around the UAL site and cannot find what someone referred to as 'expert mode'.

My second question is, does anyone ever get bumped from a 747? I am on a flight from LHR to IAD later in the month and it does not show up at all when I try to book it, so I was wondering what the possibilities were.

Thanks
