Wonder how much Eastern and American saved on weight with polished airplanes.
Since more airlines don't do it, I have to imagine the time/cost associated with keeping polished airplanes free of corrosion (especially in the norther tier!) offset -- or more than offset -- the fuel savings from the weight.
That was one of the many ongoing "battles" between Braniff (paint) and American (shiny) when American moved their corporate HQ down to Dallas.
Braniff maintained it was worth haulin' the extra weight around (flew a lot of Caribbean, Mexico, Central & South America as well as CONUS) to save on maint. costs (labor & materials) for the never-ending corrosion problem. American said "no, no, no" and suffered a lot of corrosion when they pickup up some of Braniff's routes to SA.
Who was right ??? Don't know -- Braniff's gone & American's still here. But Braniff pilots always said: "We love to fly & it shows ... "
Especially when the originators of that catch-phrase were within earshot ...
