The much more interesting thing about Fedex is about what they are going to do to replace their DC10's and MD11's. According to jp airline fleets most recent annual listing Fedex have 91 DC10's or deriviatives. They are now the only really substantial DC10 operator in the world. The oldest of these aircraft are well over 30 years old. The youngest more than 20 years old. Sure the ownership costs are very low but fuel burn and manitenance costs must be very high. They must have to start replacing them very soon now.
They have 58 MD11's as well. The average age of these aircraft seems to be around 13 years. Add these to the MD10/DC10 fleet and it looks as if around 150 aircraft will have to be replaced over the next 15 years. That will require them to acquire 1 aircraft per month before expansion is taken into account.
Logically buying more A300's (but there are not many of them around and 767's might be partial solutions but it does look now as is Fedex will have little option but to buy a whole lot more 777's and probably 747-8's as well. Therefore I think we can expect to see Fedex ordering perhaps as many as 150 new Boeing aircraft over the next few years.
It looks like a good news story for Boeing to me. I might even buy some shares in them.
