Over the years, at different times, my husband has left Bose noise-cancelling headseat, a digital camera, a cell phone, and a portable GPS in airplanes. The only thing he ever got back was the cell phone--it was noticed by another passenger and turned in at the gate. It didn't even have time to make it to lost and found as my husband realized it was gone soon after he got off the plane. Based on this, I would say your odds of getting it back are poor.
