According to Google, the Boeing 747-400 is 232’ whereas the 242’... so they’re actually longer!

Are we talking just the length/wingspan/height of the aircraft, or the usable cabin/cargo hold space?

Weight wise they are a lot less. Floor area, not much of a difference, 77W has bigger hold space.
Amongst other reasons this is why the 77W killed the 747.

It is not about the length, it is how you use it :roll:

I think A340-600 drew the first blood and the 77W finished it. :)

What alternate world are you referring to? The A340-600 killed itself. The only plane that killed the 747 was the 777 and that is because it has 2 engines. You could say the A380 did some damage i suppose as well.

What about the passenger area? How much smaller is the B777-300ER/B777-9 compare to the B747-400?

The 777-300ER has about the same number of seats as the 747-100. The 777-9 might fit a few more seats but it is still smaller than the 744.

777-300ER has smaller passenger count than 747-400 in normal, 3 - class configuration.
777-9 will be roughly the same as 747-400. It's pretty much a direct replacement of that model.

Of course, passenger count always depends on individual airline configurations.

The 350s are also doing quite the damage to the 744

A340-600? didn't draw ANY blood from the 747-400, The 777 series and having 2 fewer engines killed the B747 made the 747 redundant for passenger use. No airplane built today can beat it for freight that isn't Military based.

According to Wikipedia, the 777-9 only has 349 seats. Boeing.com states the 777-9 has 400 seats while the 747-400 has 416 seats. Somebody is not telling the truth.

It's not that someone is lying. They're just being selective with the truth by using different bases for the calculation. The 349 number on Wikipedia is taken from the Boeing airport planning PDF and is for "typical 3-class". Probably pretty accurate for real-world operation, even if on the high side.

In contrast, marketing numbers are almost always based on a fictional high-density configuration which no mainline carrier would touch with a ten-foot pole. A quick check reveals the Boeing.com figure of 400-425 is in fact based on a 2-class configuration. In service, most carriers will use three or four classes.

Further example: The Airbus website lists the A350-900 "Typical seating 3-class" at 300-350, which I find hilarious. Most carriers install 270-275 seats with 3 classes.

According to Wikipedia, in a two-class configuration, the 747-400 will have 110 more seats than the 777-9. It seems like the 747-400 is a much larger plane.

Can the 777-9 be further stretched to become a true 747-400 replacement? Will Boeing ever build a trijet with the 747-400's capacity?

777-9 further stretch? Very possible. Boeing has already proposed a 777-10. It would be a 3.3 meter stretch to a total length of 80m, meaning 40 more seats if you use the space for economy. I think this would make the available floor area more than the 744's.

Trijet? Extremely unlikely unless something changes dramatically in the field of engine tech. Much easier to mount more powerful engines. And if you want a really big plane, go with four engines. And by really big I mean the proposed but axed A350-900.

I think Boeing should move forward with the 777-10. I think the 777-9 is too small for some airlines. It seems like nobody really likes the 747-8 as much as Air China likes it.

wiki
744: 416 (23F 78J 315Y) length: 231 ft 10 in (70.66 m)
773: 365 (22F/70J/273Y) length: 242 ft 4 in / 73.86 m

so 773 can carry about same number passengers in more dense configuration.
what a question?

also interesting a load/range factor.

The 744 has a little bit of an advantage on pax count due to seating in the upper deck which the 77W obviously doesn't have. Without the upper deck the seating difference isn't much. As stated before the 777 has the advantage on cargo space.

No real world airline uses these figures. 22-23 in F? No. F seats/suites are generally larger than what Boeing illustrates in their ACAPS, furthermore lie-flat J seats take up a different configuration than what Boeing uses in their ACAPS document. They just aren't comparable to real world operations.

never say never
https://seatguru.com/airlines/Air_Austr ... -300ER.php
and even for 744
https://seatguru.com/airlines/Virgin_At ... _LGW-1.php

but actually, i quoted that numbers to compare between two, for apples and apples.


or can try this:
low F
https://seatguru.com/airlines/Air_Austr ... -300ER.php
14*60+40*38+384*32

https://seatguru.com/airlines/Virgin_At ... _LGW-1.php
14*(78-80)+66*38+375*31


more F is more difficult for comparison because seats too much different.

You realize that Club Austral and Upper Class are J products and not F right?

Virgin Atlantic replaced its 742 with A346, just the replacement market Airbus had their sights on, instead of the 744, so did Lufthansa.

It certainly drew blood, just not all that much.

as per Ferpe the 77W has 343,4 m2 cabin space compared to 380 m2 for the 744.
