A deplaning passenger came up to me and showed me a picture of the Left Hand wing with a panel floating while in flight. He said you can't see it on the ground. I saw all; over 20 screws; missing from the panel. I entered the discrepancy in the logbook.
A319 Captain reported that a passenger told him that a panel on top of the left hand wing was not secured.
