I have not heard if the -900 model has had the winglet STC'd yet? I think you all are right, if it saves fuel lets put them on.

I dont think that a winglet program has been certified for the 739.....due to the small number of 739s produced, costs may be prohibitive. CO has only twelve 739s...which are rather effecient even without winglets so its probably not a priority
