I'm also interested in this topic mostly because there is so much misinformation regarding this topic among the airlines at the moment. The United MEC recently put out this topic which compares the airlines. It looks professionally done, but I don't think it accurately reflects quality of life or the unique applications of different parts of the FedEx contract. The most notable graph is on the final page of the document which shows that a Delta pilot overwhelmingly out-earns a FedEx pilot. I have a hard time believing that is true over the lifetime of a career even if Profit Sharing is riding high for the duration.
