I was bumped on a Sunday evening flight. I checked in via the kiosk, and then asked at the gate, when I overheard someone asking to fly standby, and the gate agent saying the flight was overbooked. At that point, I said I would volunteer. After boarding was complete, they had two empty seats, and were looking to fill those with people who'd volunteered to be bumped. When asked about me by another gate agent, the first gate agent said, "She was the first volunteer, so she's not an option to put on this flight." I'm non-elite, so that didn't figure in to the equation. I would ask at the check-in counter, and then ask at the gate, assuming you've been told the flight is full, as soon as you get there. I would arrive a bit earlier than normal, and be sure to go straight to the gate. Good luck!
