Feb 11 UA877 ORD-PHX A320 ^ at least at least for awhile. This was an interesting flight, as we had a medical emergency (with passenger on the floor in the back galley) for almost the entire three hours. I switched to iPod eventually and then went back to Ch 9 a little later when it felt like we were turning and I wondered whether we might be diverting. I checked again about 10 minutes before landing and it was quiet, so I guess it went off at some point.
