This question came to me from the Hawaiian/Aloha post posted earlier. I know that Alaskan and Hawaiian/Aloha fly combi's, but they have special waivers from the FAA. Why does the FAA frown on combi operations by US carriers? Seems pretty damn stupid to me. I know Fed Ex/UPS and others would hate the idea, but why does tht FAA have the position on combi's that it does?
