Now that CO has put winglets on its B757-200s, how long b4 their -300s get them? Anyone know of other B757 operators keen on the winglets being added to their machines? Also wonder if the winglets on the B767-200/-300 would improve fuel burn performance?

CO doesn't have the 763, they do however have the 764. I believe that the 764's wings are "raked". I believe that the 764s wings already have an advantage over the conventional wing. The 764 and teh 753 have great economics so I do not know if the benefit that winglets may bring will justify the $$$.

I definately just replied to this topic but evidently my reply has evaporated.

The 757-300 is not slated to get winglets and, if it's not for CO, I doubt it'll ever get any.

The 753 will probably not get them anytime in the near future, mainly because of routes. The 753 is flown almost entirely domestically, while the 752 is the one flying the European routes. This means that the winglets would not help the 753 as much, as the flights are generally shorter.

APB has a 767 winglet program, though no takers yet. AC will likely be the first. Fuel burn and performance would definately be aided. Anyone for AM to buy them?

The also have the 762ER, which could definately benefit from the winglet

The RWD (Raked Wingtip Device) on the 764 is actually more efficient from an aerodynamic standpoint than blended winglets. You could not put winglets on without taking them off and you would likely get a net loss in performance
Winglets, on the other hand, could stretch the range of the 753 to Europe if CO wanted to. Any improvement they give the 752 would likely be similar on the 753. The winglet program on the 752 is not really about economics per se (though that will be helped), as it is already very economical. It is about extending the range to allow flights to Eastern Europe
