The part about looking in the back makes me laugh ! A couple of years ago my luggage on the way back from NZ got caught in the big delays at Heathrow. One big travel bag and one road bike in a soft case. Not too bothered, you generally get it eventually.
Guy turns up with a truck with travel bag. Swears blind that is the only thing for me , even goes back to the truck to check, comes back empty handed. I reason/persuade/cry enough about the bike, and the fact that I have two texts saying delivery of each bag at the same time.
Eventually he lets the crazy woman look in the truck herself to confront her own insanity. The bike is right there !! Its huge and in a bag with a big labe sayig BIKE.
So yeah anyway long boring story short, but always look in the back of the truck !!
