So... don’t know if you saw, but N303AS was repainted. What makes that unique is it’s one of only three aircraft in Alaska’s fleet that do not have winglets. I guess this gives you a look at what a 737-400 in AS’ new colors would have looked like. While I don’t think the winglets look bad, I do like the nice clean look of jets without them.
