I know it's been discussed many times but after looking through the search I couldn't find an answer to a specific question.

Is a bump more likely on a 200 seater or a 50 seater? If going for a bump which would be the smarter segment.

Anyway, I'm on a rewards flight to go back home for christmas and the flight is BDL-STL-SFO with the first being a 50 seat flight, second 150 seat MD-80. The itinerary is for Dec 21 (Wednesday), both planes showing currently to be full.

What's the likeliness of getting bumped, just from peoples experiences?

Do they provide rewards travelers with additional free travel or will look at me funny for volunteering on a rewards flight at check-in?
