Flew home from Dusseldorf on Thursday. When I arrived at SFO, noticed my tablet, which I had put on the floor of the flight from DUS to ORD along with my camera, was not with me. I had taken it out figuring I'd be blocked in the window seat once the person next to me reclined. Ended up with an empty seat there. Didn't use my tablet during the flight as I found enough video on the AA tablet. Did use the camera and after the pre-arrival snack put it back in my bag. Just completely forgot I left the tablet on the floor come arrival at ORD. It was probably under the duvet that was also on the floor at end of flight. Called the EXP desk from Walnut Creek BART on Thursday night as I was heading home. They gave me the phone for lost and found at ORD. Left a message with my details there. Received a call from Rita at lost and found Friday morning. No sign of my tablet yet but she told me property from international can take 24-48 hours to get to her. Rita just called back. She has my tablet and is arranging for it to be shipped to me on Monday (at my expense--I would not expect AA to pay for this). Very welcome news as I was not optimistic it would appear. Thursday was an odd travel day for me. After I checked in at DUS, I left my travel wallet on top of my rollaboard, and didn't notice it wasn't in my pocket until I was halfway to the C terminal security gates. Fortunately, it was still sitting on top of the rollaboard. When I arrived at Walnut Creek BART before my bus connection home, I had lost my Clipper card, a stored value card that recharges from a credit card when the balance gets low. Had it when I entered BART at SFO, and no idea what happened to it in the next hour. Wasn't anywhere around my seat. Bought a paper ticket to get out and called Clipper to block the card and reissue a new one. No activity on the card that evening. I probably need to stay off airplanes for a while. Fortunately, next trip isn't until December. Hope I don't make the same mistakes all over again.
