I am not sure what is considered "so few", as my records show that 27 of the 58 aircraft have now been retrofitted with winglets. Specifically, fleet numbers 345, 351, 353, 354, 356, 359-362, 364, 365, 370, 372, 373, 377, 380-383, 385-391, and 399. That comprises nearly half the fleet. Admittedly, the pace seems to be a bit slow, but that is probably due to the fact that the aircraft is usually out of service for approximately a month for the work, so American does not want to have too many idle at the same time.

AA is slow at getting this done; didn't they start in 2009? More dragging on: 757-200s getting refitted with new seating. 737-800s getting new seating as well. Next up cabin reconfigurations on the 777-200s to remove F, adjust Y for Main Cabin Extra, add WiFi, and upgrade the AVOD and power ports. That should take a good 5 years at this pace.
Every aircraft type that is staying in the fleet is getting or having something done...who knows how long this will drag on.

The planes usually don't quite take a whole month - I think it's usually around 20-25 days. All aircraft receive the winglet mod and the flat panel cockpit display mod during the same visit.

I believe they did. In December of 2009, I flew on a 763 from LHR to BRU and it had already the winglets, can't remember the registration. Indeed, at that time most of the 763s at AA had not their winglets installed yet.
I flew on one in January of 2011 from MIA to JFK (I remember how beautiful the sunrise was, upon leaving MIA) and the one I was on (sorry I didn't look at the reg) was still not equipped with winglets, maybe it is now but it was not at the time I flew on it.
And none has ever crashed since the first one was delivered back in 1988. None has ever been lost and none has yet been written off or sold second hand to another company.
Quoting N62NA (Reply 6): So... at this pace, they'll be done around 2015/16.
And by then, the oldest 763 will be already 28. The 200s will probably be gone and the oldest 300s will be getting close to retirement. However, I don't think that the last one will leave the fleet before 2020, if not later, because the youngest ones date from the early 2000s.

If i recall, they are not rushing them to get fitted as stated, it takes a lot of time.
They are probably waiting for the aircraft to go into overhaul D checks before adding winglets. This way, the airframe was already going to be out of service, and so easier to make the changes also.
On another note. DL and their B757s winglet addition. Are they adding them to all of them? It seems they are taking their time in getting them on those birds! I know they have a lot but during winter period, when we see them here in GCM, they mostly dont have winglets

Not in this case. As I mentioned, there is a special line set up in TUL for winglets and avionics upgrades. As far as I know, there isn't anything going on during scheduled maintenance visits in AFW.

Quoting boeing767mech (Reply 13): Considering you have to unskin the last 20 feet of the wing, it takes about 3 weeks to do the mod for the winglet. So you don't just pull an airplane off the line and slap the winglets on.
wow - 3 weeks is a long time!!! So it's about the same for 737 & 757?
As they are done in the house at AA, some send them to Japan. To safe fuel and time couldn't Boeing do them for there customers (if there is no C or D-Check)?

What's the point you are making here? I don't see any relevance to the discussion here.
This is not something great or extraordinary, the fact that none has been lost or W/O is something I expect from an airline.
Your statement gives me more of a feeling that it is something special that those AA 763's are still flying....

Quoting N62NA (Reply 17): Slightly off topic.... but apparently they can do a Gogo WiFi install overnight - why haven't they done that on the rest of the 738s and on the domestic 757 fleete?
I don't know about the 757s, but the 738s are coming along. Regardless, I'm getting sick of the slow pace of the install. AA has been pushing its Wi-Fi connectivity in advertisements for several months, yet unlike DL, it's never a sure thing that gogo will be available.
As a loyal AA customer, gogo is a low-hanging fruit service enhancement, and I can't for the life of me understand why it wasn't a priority a long time ago -- even before the company went into Chapter 11. Frankly, it seems like the company has stepped over a dollar to pick up a penny by throttling the rate of install. Said differently, the impact of services like gogo can't always be directly quantified on a pure P&L basis, but it does create customer goodwill on some level, which in turn influences future spending decisions.
Back to the topic, I do give AA credit for its overall winglet program. AA was quick to adopt the benefits of winglets and was much more aggressive about it compared to its peers. Has anyone seen any numbers comparing the total fuel savings across carriers?

To answer some of the questions posted here:
1) The 767 winglet program is slowly progressing however it is only being done currently during the off peak travel times as AA needs every available aircraft for the peak travel months. There was a suspension of the program for several months due to some technical issues that cropped up however they have since been resolved. Although the actual installation of the winglets is approximately three weeks, AA is using this time to install new avionics in the flight deck (replacing the old CRTs with new LCD screens and upgrading all the computers and navigation computers as well) to make them compatible with the new ATC requirements worldwide which adds a few days to the downtime. All the winglet installations are done in-house.
2) The reason that the GoGo WiFi isn't in the 757s and 767s as yet is that GoGo will be rolling out a new satellite augmented system next year which will allow Transatlantic and Transpacific internet connections. The new system is not compatible with the existing system so instead of installing the system twice AA opted to wait with the installation until the new service is available. The first aircraft that will have it installed is the 777-300 coming late this fall. Also with the 757/767 aircraft being used predominately outside of the US mainland (the only place GoGo is currently available) it would not be good to mislead passengers into thinking they had WiFi connections for the entire flight when in reality it might of be for the first hour or so. The 767-200 aircraft all have WiFi as they are used solely on US domestic routes were GoGo is currently available.
In the meantime the 737 fleet is getting it installed as they rotate through Tulsa on longer maintenance checks (the new aircraft are getting it installed prior to entering service). Believe it or not, the Gogo system is only being used by a very small number of passengers and is not the money earner that people might expect. Still as the competition has it, so everyone is forced to have it. To recoup the installation costs and subsequent downtime on the aircraft unless the aircraft is already scheduled for a check would take a very long time just based on the current amount of users. Hence it is done in combination with other work that the aircraft require from time to time.
As fuel savings of the 767 winglet, I remember reading somewhere that it was around 5-6% of the fuel burn however there are many factors that determine the exact amount. I think it is safe to say it is probably 3-4%, which would make the installation economically viable.
