As a novice I am curious about some of my assumptions and desire for facts about the gaps between a 767 and a 787. I am very familiar with all the very cool features on board (if you've flown United lately you cant miss Smisek gloating over the pretty new plane) but I haven't even flown a 787 yet. Darn!
In December I was on a United 767-400, 6 times, long haul. All in BusinessFirst. It is such a beautiful and comfortable airplane. But the 787 is better, a "quantum leap" forward. Ad to my great experience on the 764, I also saw the pics and read here about LAN's (and ANA's) new 767's with winglets with a fair amount of pomp and finally the impressive fact that the 767 line is still running for 33 some years with no end in sight yet.
So, what are the X vs Y facts between the two? Not the increased cabin pressure, but the efficiency factors. Are today's plethora of 767's (the newer international ER models) still turning a decent margin and on the same route how much better is the 787 doing so far?
Last: in particular I am curious about the virtues (if there are) of the 764, an ac I have come to like very much. (I've only ever been on UA in a lie flat BF seat, I haven't flown Delta's) if UA could, would they have wished for more?
Thanks a billion in advance!
The world is missing love, let's use our flights to spread it!
In round numbers comparing the 787-8 and 767-300ER:
The 787 flies 2,000 nm further
The 787 caries 25 more pax
The 787 burns 20% less fuel
The 787 costs 30% less to maintain (airframe)
The 787 costs 15% less to operate (CAROC)
The 787 costs $25M more to buy (list price)

If you put all the competing craft on the same scale graph for MZFW v Range, the huge gap between the largest narrow bodies and the 767 family becomes apparent.
There is a huge void here if someone comes up with the correct aircraft. Part of the reason this has not been filled, may be that it is not clear wether to go large narrow body or small widebody, whereas by the time you get to 767size a widebody is fairly clear.
I think the gap won't be closed until both Airbus and Boeing introduce totally new narrowbodies which I think they will give the potential for 250 seats out to 4000nm+.
Many here say that the 788 will cover this gap too, or a super stretched A321/739. I think it would be vice to design the NSA with some of that capability in mind from start, maybe a stronger uc,wing root extensions and higher thrust engines that only that larger model has, otherwise same stuff as the smaller models 160-190 seats up to 3500nm range.
If you could make a bigger plane with the same OEW as the current NBs that would probably make a larger more capable NB possible, one would have to minimize the special gadgets though to recoup the cost. For some routes flying a WB is abusing it and the current NBs cant make the range but otherwise fit the size needed. Depends on how the fuel cost will grow I guess, if we see another steep climb airlines will as for better optimized models.

Quoting VC10er (Thread starter): All in BusinessFirst. It is such a beautiful and comfortable airplane.
A question, is the comparison really about the a/c and their technicalities or the equipment that the airline chooses to install internally?
Technically only the difference in air pressure, speed of the a/c and noise of the engine are a/c specific, other than that, your comfort and impression of the a/c is strictly up to the airline. Some have ben on 767's whose interiors are "ratty" and the call the a/c obsolete, another airline can have the same a/c, same engines but updated interiro and its fine and are praised by pax.
Quoting sweair (Reply 3): The seating in the 767 is the best ever, 2-3-2 in economy, no cross section comes close to being this great.
Quoting scbriml (Reply 4): Personally, I prefer 2-4-2 in an Airbus A300/A330/A340 - no discernible difference in seating and a wider, more spacious feel to the cabin.
Take the two quotes above ,one is claiming that less people in a row based on the cross section of the a/c is more comfortable, the other is claiming that more people in the row with a larger corss section is more comfortable.
At the end of the day, how the airline chooses to cater to pax inside the a/c is the key for the majority of the travelling public, and in that regard, it really is a crap shoot which the OEM's really do not control.
Not sure how the 764 compares with the 788 in efficiency, however, when compared with the 763, the 764 has a lower CASM. In fact, the 764 has a lower CASM than the A332, despite what Airbus fans want you to believe; the A332 only sells better due to greater range and cargo capacity.
As for UA buying more 764s, I would actually say DL would be more likely to buy more than UA would. DL has been stocking up on oddball aircraft types in recent years (MD-90 and 717 come to mind), and there are indeed some transatlantic routes that don't need the added range and cargo capacity of the A332. The 764 has worked flawlessly for DL across the Atlantic, regardless of what Airbus fans tell you. In fact, if UA were to dump its 764s, I would guarantee with 99.99% confidence that DL would acquire them almost immediately.

Agreed, but the VAST majority of 767s have 2-3-2 in economy, and the VAST majority of A300/A330/A340s have 2-4-2 in economy.
Time flies like an arrow. Fruit flies like a banana!
Looking at these numbers for interior cabin width, and how many seats across they can comfortable have, there seems to be a gap that can be filled with a new interior cabin width in the 14' to 15' range, seating 7, 8, or 9 abreast (based on 16" to 18" wide seats). 9 abreast seating would be crowded with 2 18" wide aisles and only 16" wide seats (14' wide cabin). No, I am not recommending this type of configueration to anyone. An 8 abreast seating with 17.5" wide seats would leave 2 aisles about 20" wide (14' wide cabin).
Something like this could be the next NB airplane, we could call it the 1.5NB, or NB1.5, even though it is not really 1.5 times as wide as todays NBs (nor are some of today's WBs). It is, of course not as wide as todays WBs at 15'6" to 20' wide, but making it 15' wide would put it right next to the narrowest WB today, the B-767. A fuselarge in this width would be the smallest practical to be made with a carbon fiber material, a sort of mini B-787. This would produce an airplane with about a 4,000 nm range, clearly a TATL airplane, as well as west US coast to Hawaii and TRANSCON. with a decend pax load and cargo. If this design were the same lenght as the B-739 (138' long), it would add some 50 seats to the AS configueration (32" pitch) in Y seats. On an AC A-321 (146' long), it would add about 54 seats (32" pitch) in Y seats. Both of these are based on an 8 abreast seating. A new design airplane like this would need 2X 28,000 lb to 30,000 lb thrust class engines such as the new CFMI LEAP-1A or -1B engines or the P&W GTF and have an OEW around 95,000 lbs to 100,000 lbs, MTOW could be near 215,000 lbs. This makes the basic airplane lighter than the B-739ER or the A-321, but with a higher MTOW for the additional range. The max fuel load would be around 6500 US Gallons, or about 42,250 lbs of fuel, leaving a max payload (pax, baggage, and cargo) of about 72,750 lbs. The cargo capacity would be about 1900 cuft to 2000 cuft., or about 12-13 LD-3s.

Quoting sweair (Reply 11): Quoting KC135TopBoom (Reply 10):
Can you build a twin aisle small body in the current NB weight class? I think the NSA will still be plain old 3-3 and as badly stretched on longer routes to be good at 500nm routes.
The 215K MTOW I suggested is a lot less than the B-757, MTOW up to 272.5K.
Quoting idlewildchild (Reply 12): Though all new aircraft have bugs he led me to believe some of the bugs on the 787 were pretty serious, including fuel line issues.
All of the issues are being addressed, including those thought to be serious, like the fuel line issue and the GEnx engine issue and about the same seriousness as the A-380's rib feet cracking problem, which effects all current A-380s. The other B-787 issues are minor in nature.

Quoting 1337Delta764 (Reply 8): The 764 has worked flawlessly for DL across the Atlantic, regardless of what Airbus fans tell you.
The funny thing is that the 764 would probably be more robust of a long haul aircraft, and sold better, had it not be for DL. Boeing built the 764 to satisfy two customers, CO and DL, however both carriers requirements of them were for totally different missions. CO wanted the 764 to replace their DC-10-30s which were the backbone of their International fleet flying long range flights like EWR-SCL, EWR-HNL, EWR-FCO etc.. DL wanted them to replace their L1011s on domestic legs such as ATL-MCO, ATL-FLL, LAX-HNL etc..
Boeing had originally designed the 764 for longer range, which had a larger wing, however DL needed something smaller to fit into their domestic operations. Thus the aircraft that was developed was a compromise between DL needing something with a smaller wing to fit into gates in places like ATL, FLL etc. and CO's need for intercontinental range. Later during their bankruptcy DL reconfigured the 764s for International flights and took them off the ATL-Florida, Las Vegas, California runs. If the 764 were developed as originally intended, more range and bigger wing, it probably would have sold much more than what has been built.
CO originally had 26 764s on order, however they converted ten of those to 777s as they shifted their attention to opening up Asia from EWR.

The 767-400ERX did address both of those issues through higher MTOW, a tailplane fuel tank and more powerful engines. And yet it only secured three orders from Kenyan Airways and was eventually cancelled along with the 747-500X / 747-600X (as it was to share engines with that program).
The 767-400ER gets a bad rap because of low sales just like the A340-500 does. However, the planes were designed to fill a need for some important carriers and Boeing, at least, has a long history of doing special models for their customers.
However, there are indeed missions where the 764 is more appropriate than the A332, and that includes a large portion fo DL's transatlantic network. Not all of DL's transatlantic routes need the A332's added range or cargo capacity.

Quoting ADent (Reply 1): Boeing built a 767-400 a couple of years ago for the US DOD. So Boeing can, and will build more for the right price.
No they can't. The supplier can no longer make the Flight Deck display system. It would have to have a new display system designed. The DOD airplane was built more in the same time frame as the DL and CO airplanes. It was more than just a few years ago. I think it sat around for many years before being delivered so that might be what you are thinking.
Britannia apparently came close to ordering it. I would have loved to see AA buy it but the different (and much more modern) display system of the 767-400 than the 767/757s in their fleet deterred AA.
Excellent airplane by many accounts. It was just a bit under-ranged and under-powered for some missions. As some other posters indicated, it was designed somewhat for some DL needs which limited some of the missions other customers may have wanted.
The 767-400 is a lot like the 717 in the respect that it's an outstanding reliable economical well performing airplane. Customers that have them really like them. Other factors than the quality of the airplane doomed it to low sales - lack of flight deck commonality with other models being one.
You were after something in size between a A321 and a 762? But how efficient would a frame like that be on 500nm routes that many 738s fly?
Most of the NB market is really short routes, that however does not take away the abuse of WBs on long and thin that a more capable NB could excel at. Many here even think 788 will be good at 4000nm routes. WB fan boys I call them

Quoting UALWN (Reply 13): And yet only 37 764s have ever been sold, compared with 576 A332s...
The better cross section of the A330 and the much higher range account for this difference.
Ultimately the cross section and the wing were the two big weaknesses the 767 faced in competing with the A330. Neither one is easy to fix, which is why we got first the 777 and then the 787, rather than more and bigger 767 derivatives.

To try to answer the original question - - although I am poorly equipped to do so - - the 763ER winglet is fairly low in cost, depreciated financially and is still a very good performer. We can expect it still will last 10-20 years more service with major US carriers.
The 788 is being used primarily for its long range. For missions the 763ER can't do. Also, the 764ERs will keep flying until way past 2020. So despite Boeing's advertisements, the 787 is not exactly a 767 replacement. What it really is, is an A330 replacement. That must satisfy Boeing very much.
There isn't crystal clear evidence the 788 burns less fuel per hour than the 763ER winglet. Since 787 is bigger, and a little faster, the per seat-mile efficiency of 787 will crush 767 as a new-build airliner. This does _not_ mean the 767 is functionally obsolete - - it will holds its own as a junior sister fleet of the 787 for many years.
