PCL Flt Ops,
FedEx has a 4 week schedule (8 times) and 5 week schedule (4 times). This is because the schedules are built beginning on Monday to accomodate the beginning of the business week. On a 4 week schedule the min days off is 13 days off and the guarantee pay is 70 hours with average pay around 73 hours for a line holder. On a 5 week schedule the min days off is 16 days and the guarantee is 89 hours with average pay around 93 for a line holder. These figures are give or take an hour.
The schedules depend a lot on the airframe. The 727 and Airbus basically do mostly domestic flying. However, in both you do have the opportunity to fly internationally (727 in So. America and the Airbuss in Europe and Pacific). But, basically the "hub-turn" night-flying schedule is week on and week off. However we do have a tremendous amount of day flying which has a variety of scheduling opportunities. The MD-11 has everything as far as scheduling diversity. It has the week-on and week-off hub-turns, day or night out and backs, 8-12 day international trips, or 3-5 day domestic trips.
As far as the typical flying (in the domestic system) for Fed Ex. For the "hub-turn" during the night you may fly one or two legs into Memphis, sit for 2 to 3 hours, and then fly one or two legs out. I don't think we do any 3 legs in or out of MEM at night, but I have not looked at the 727 bidpack in quite some time. At Memphis there is also a day sort. This sort is almost as big as the night sort. For this flying you have out-and-backs from Memphis, which I guess is a good deal for people living in Memphis. Basically, you would take off around 3 or 4 in the morning from Memphis (fly the outbound from the Night sort), go to the out station (PHL, EWR, DFW, ORD, MCO, etc), sit for a few hours, and then fly back to Memphis. Home by noon. Or you can take off out of Memphis at around 4 or 5 in the afternoon, fly to the out station, sit for a few hours, and fly back to MEM. Home by midnight. Right now at FedEx the pilot schedules are very diverse and offer a great deal or options. Good if you are senior. There are a lot of different types of flying available. To categorize it is very difficult. I hope this gives you a bit of an idea of the flying (at least domestically). Also, keep in mind the same thing that goes on in MEM also happens at IND, only on a little smaller scale.
