Last year, I got $600 once for a 9am from ATL-DFW. First confirmed seat was at 1:30, but I managed to get on the 11am standby. I think I was GM (maybe FO?) at the time?
I don't think status has anything to do with the offer amount. Nor does fare paid. You can argue, but if they can get someone else for $200, why pay you $400+? All they need is a seat. They don't care whose butt used to be in it. That's why it's called VOLUNTARY denied boarding.
I know that as DM they will provide hotel vouchers for stranding you overnight, even if it's because of weather. I would assume any decent VDB package requiring an overnight would have hotel included.
