The Airbus A321 will be the first family member to receive the upgrade, increasing the US transcontinental range to be more competitive with the Boeing 737-900 and to target the Boeing 757 fleet, a prevalent aircraft in the US legacy carrier operation. American, Continental, Delta, Northwest and United airlines all have large 757 fleets.

A real benefit of these in the USA would be performance out of places like BUR and SNA, where the winglets would allow for a higher TOW, meaning more usable fuel, meaning better payloads transcon out of these airports for A320s.
Of all the things to worry about... the Wookie has no pants.

I'll believe it when I see it, because Airbus has already tested several winglet designs in the past without success. If this does happen however, then it would mean that the recently tested AP winglets proved a to be a good design that worked with the A320's wing.
However, I'm surprised at the mention of sharklets. That design hasn't even been flight tested yet, it seems premature to already be considering it as an option.
A 2-4% fuel burn improvement is a welcome upgrade, but won't quite put the A321 into 757 territory (although it will slightly eat away at it). An A321WL would still not be able to do transatlantic, but would at least be more comfortable doing US transcon than it is now.
These winglets could also be welcomed by airlines operating A320Fam a/c on longer routes, too, like Western EU - Russia or UK/northern EU - Canary Islands.

Several variants were tested in the last few years.
I guess bigger more efficient wing lets require structural strenghtening making them less suitable for retrofits. After innitial testing probably designs were adjusted & windtunneled and now look good. The next one to be seen on A320 proto will probably be close to the final design.

The A321 can't take pallets, either, and the AKH container can't be interlined with any non-A320 family model. I also imagine most A321's are bulk-loaded just like 757s are.
I'm in agreement with you. Keesje, that most missions under 4500km are better served by the A321-200 and 737-900ER. However, when you need long legs or strong performance, when it comes to narrowbodies, you still can't beat a 757 and that will keep the model popular with at least one niche, especially with the winglets adding 400km of range and reducing fuel consumption by 5%.

For Airbus to upgrade the 321 to specs of a 757 wouldn't they have to develop a new wing and landing gear box to hold a heavier aircraft and engines? How long would that take them to do.
If Boeing is to up the performance of the 73G series, wouldn't they too have to develop a new wing and gear box so that they can put more efficent, powerful engines on these birds? As one said, it will be difficult for Boeing to use a more powerful, advanced engine since the 73G sits so close to the ground.
What's the height difference between the A320 & 73G series'?

surely Airbus would prefer to use their own sharklets as they dont need to license the design off AP? however I think they need to get AP on board as their designs have done wonders on the 737/757, wouldnt an A330 winglet help close the gap on the 787?

For USA Transcon, Northern Europe to Canaries , Central Europe to Gulf Area, North America to South America, there are many routes which are just on the limit of the current A321-200. So every 100 miles more ranges opens new routes it can do with full load, and on all routes it can do it is a hot candidate. The corner the 757 still has just gets smaller - and can be done by enough existing late 757 for indeed a decade or more.
The increased range only slightly affects economics, I read an A321-200 needs about 50l more than an A321-100 per hour.

I wonder if JetBlue would consider getting the A320 with winglets..also.I was thinking: Would the A320 be the same thing as the B757 with winglets? I was thinking that the winglets would give the A320 more range, which would be great.
Bring JetBlue To Mexico City! (TLC and/or MEX would be great)

Quoting CALTECH (Reply 18): Where are the Airbus fans who said the A-320 wing was perfect, but then a improvement makes it more so. So the Boeing 737 NextGen wing is more perfect than the Airbus wing right now ?
I like how you phrased this.
There is no perfect wing, as we all know. They all should have greater wingspans, but weight reasons cut that back. As we improve our materials... wings will improve. Not to mention new cross sections are still being invented.
Winglets improve the effective aspect ratio. Every wing out there is an 'engineering compromise' that could have been better if certain technology was more mature...

Be interesting and nice to see retrofits done. And what JetBlue does.

Yuck, I know looks aren't important in aviation since it all boils down to the almighty dollar, but to me an A320 without the standard wingtip fences is not an A320 at all. (I'm not speaking in terms of technicalities, I know that the first 320s didn't have them at all) That bird is an ugly duckling to me.

Weight AND gate, I suspect.
I also suspect the economic paradigm was slightly different in the days when these planes were conceived, and the convenience of the smaller wingspan was at an acceptable price.
That, and as you rightly point out, the manufacturing advances made since then....

I believe the initial idea of putting new winglets on the A320 came from Jetblue.
A Jetblue A320 was fitted with 2 different seats of winglets for comparisons in 2006. This thread has been cleaned up like no thread before with the majority of posts gone via the reference post deleted procedure. It used to have this picture:
As you note, it was a different economic situation. Optimizing for < $30/bbl oil results in a different aircraft than oil at ~$70/bbl.
Quoting Keesje (Reply 23): A Jetblue A320 was fitted with 2 different seats of winglets for comparisons in 2006.
It was a wake up call, to me personally, when neither set was approved/accepted. It was more than a little bit surprising that neither set was not going to pay off back when oil prices were 'shooting to the moon.'
What I'm most excited about is the range improvement. Ok, its small, but if IAE would improve their engine too...
Lawn set to brown: dang drought.
: Personally I think the 320 looks great with the winglets (presumably the AP variants? Who knows at this point..) with the Airbus livery. It's a shame
: The winglet itself, last December they tested a new set of winglets designed by Aviation Partners, the same guys that created the 737-s winglets Chee
: My guess right now is that JetBlue (B6) will be the primary customer right now for the A320 upgrade with winglets, all being installed as part of each
