I was on an AA PVD-ORD flight on the 20th and it was oversold by a few seats. They didn't announce it - only quietly put up a framed sign asking for volunteers. I was gonna go for it but I would've had to take a 6am flight the next morning.

Funny, though, .. the GAs didn't specify the compensation amount.
Looks like my flights on the 29th are oversold as well.
