FedEx currently has two pay rates, narrow and widebody. Both ALPA and flight management appear to want to have individual equipment pay in the next contract. In any event, the A380 would be either under that or as a "tall body", so it will be broken out. Regardless of anything else, at this point I would say that it is improbable that we will be taking any pay cuts.
10 firm, options for another 10, rumor of many more.
