I went in for an interview today for the air hub in Louisville. I applied for a part time package handler position but tonight I noticed that my application has changed from 'active' to 'on file' and it now says air handler under position instead of package handler. I really don't know what an air handler is (I've browsed the forums, something to do with loading and unloading planes maybe? nothing is particularly explicit). Can anyone explain to me what might be going on here?
