I actually had a conversation with our delivery person from purolator, he says there are 47 aircraft flying in Canada for purolator and 1 for fedex, the rest of the fedex are going to the states......well what ever. I told him that I like fedex because of the aircraft choice they have made!!! Purolator uses little aircraft.....!!!
I think the operating cost are the same if you choose a A300 or a 757, it still takes a lot to get the aircraft airborne, fuel......etc and why not have the room when you need it......these days there is so much being shipped, I wouldn't be surprised if most of the aircraft are full!!! Would fedex still be in business if they had empty aircraft? They are really sucessful, and if they have orders for the A380....you do the math.....good question, but could be better phrased
Drive it like you stole it!
