Nope, I didn't want to tempt fate. This is my first bump ever -not that I have not tried before, but AA usually puts me back at the last minute when I volunteer-, so I took a normal coach seat. Now that I know it is possible I will try that on the return leg, this friday (CDG-BOS-MSP), and since the snow storm from this week has cancelled many flights to the east coast, I'm guessing my chances will be higher due to the volume of delayed passengers stil trying to make their way home on friday.
