I sat in seat 10A. My anorak was in the locker above seat 10D, with my computer and other people’s items. My hearing aids were in the side pocket of the anorak; the pockets have no seal. During the journey the anorak got thrown around bit when other passengers accessed their items. The hearing aid box fell out, and was not there to be seen when we left the aircraft. The hearing aid box was similar to the one in the photo.
