Hi 00 - I was reminded just yesterday that you have been a bad boy, but I'll pass on some advice if you tell us if you are rooting for Gore or for Bradley:
1) You cannot have it noted a day prior. You have to volunteer at the gate where the flight is departing.
2) If you are voluntarily bumped, arrangements will be made for you to travel in an alternate flight and you will be given vouchers. I have never been involuntarily bumped so I do not know what happens in that case, but I presume it would be the same.
3) If they put you on a different airline, then double dip. Fill out a form at United to get FF miles on United, and also get miles on the other carrier.
4) If there is no flight that day ask that they put you up in a hotel and give you a meal allowance. If your next flight is several hours away, ask for a meal voucher.
5) The vouchers you receive are good for a year, but cannot be used within 72 hours of issue. The vouchers can be used in conjunction with coupons, and for maximum mileage book with United Connection on PC to get the online booking bonus (assuming it is still around in 2000).
