No, if you pay for next day guaranteed delivery, and you get it. What kind of guarantee does any airline give about bags or making a connection, or a seat on the plane for that matter? What about those people that by tickets on the oversold flight and then do not get to ride. Maybe at christmas next year I can arrange to have your package just left on the ramp. I might even offer it a free voucher for $5 bucks of food.
Well we can get them there the next day too and we don't charge extra for it. I mean how hard is it to get there the next day? Big deal, we get the overwhelming majority of our passengers and baggage to their destination within 14 minutes of their published itinerary, let alone the next day. When you can come up with a delivery system that guarantees most of your freight gets delivered within 14 minutes of scheduled delivery, then let's talk, but a 24 hour window is easy.
