We had one of our 5 checked bags go missing from our return flight VFA-ADD-IAD. The only contact we have is an email in ADD. I found their cliam form online and emailed it in, but no response. Has anyone had this issue, and have a better way to get ahold of someone? There was No One at IAD to report to, and we had limited time to make our connecting flight to hang around check-in or go tot he ET outbound gate at IAD.
