After running around Charles de Gaulle, it was nice to have a pleasant, comfortable ride that was at least 70 minutes faster than the A330 we used on the same route 5 months earlier. The cabin was dated though.
The last time I checked the 747 was the fastest subsonic airliner in the sky. Even faster than a 757.

most of the heavies cruise at .84-.86, 757/767 wing likes.80

Is it the same with the newer planes, i.e. the 777/787 with a more modern wing design?

a bit more than that, 777 was 100% cad/cam, 787 is a "plastic" airplane
, those two are significantly more advanced and efficient than the 757/767/747Posted on 6/28/19 at 10:50 am to 777Tiger
I find the A320s much more comfortable as a passenger than the 737s... it's one of the reasons I've started using Delta more often, even if they don't have the route system out of the DC area that can compete with United or American (the other reason is service. Delta, I find, is just a much better overall experience when flying domestically).
I love the A350s and 787s. Such great planes and great experiences. They tell me my jet lag is supposed to be better... and it may be. But I'm also using points now to fly business class on long haul flights, so I can't appropriately judge.
To tie my comments back to this thread, I've flown on 777s, 787s, A380s, A350s for long haul, but I still haven't flown on the Queen of the Skies. Hopefully I can make it work one day before she's out of commission.

I too flew in from Miami Beach BOAC.
Didn't get to sleep last night.

it's true, those two keep the cabin a little lower and increase the humidity a bit to fight the hydration that occurs on long haul flights

good call, well worth it

BA jumbos are old as shite. Some are nasty.

78 is fast af.

Though in a different time period, I think Convair's 990 were even faster. I know it had a huge thirst for fuel to achieve that distinction.

Man, it was a dreadful flight.

Last time I flew on a 747 was Denver to Munich with Lufthansa it was miserable.

Yep, those things could cruise around .89-.91ish, back then they didn’t care a whole lot about gas, my company had a few of those, before my time, used to drop down into the teens and sightsee on transcons

A340 = will be completely phased out in the next few years.
The Lufthansa group just actually said for their Swiss Air A340s they are going to upgrade the cabins to match the interior they are putting in their new 777Xs... wouldn’t be doing that unless they planned to keep milking it out a little longer with then... I was quite surprised when I read that with everyone phasing out the 4 engine older birds.... talk about an airplane with some of the worst take off performance; just watch an A340 trying to gain altitude after rotation....

Took a TWA 747 to Italy and back
I took one on TWA to London and back in 1972, and that was the only time I've ever been on a 747.
Last year at Heathrow there were plenty still at the gates.

A bit more info about this --the carbon composite airframe makes this possible:
They made a big deal about that on that Netflix show I mentioned before. They also discussed how the composite didn't serve the purpose of a Farraday cage like the metal frames do (protecting the plane from lightning strikes), so they had to add a thin layer of metal foil to the outside to serve that purpose.

Theories abound about what causes and how to beat jet lag. But it’s widely accepted that some of the main symptoms associated with long-haul flying are due to altitude and dehydration, rather than an actual time zone shift. As a study in the New England Journal of Medicine noted, the pressure in a typical aircraft cabin is similar to the altitudes on land where altitude sickness (also known as mountain sickness) occurs.
Conventional aircrafts are pressurized to mimic being at about 8,000 feet on land, similar to Bogota, Colombia’s high-elevation capital. But these newer jets’ more flexible composite material means, unlike metal, they can withstand more interior pressurization without damage to the plane’s structure, allowing an in-cabin atmosphere similar to an altitude of about 6,000 feet. That could make a significant difference to passenger comfort, the study found.
In addition, the newer planes’ cabins maintain a higher humidity level by controlling how much of passenger-generated humidity (from all those exhalations) stays in the cabin, rather than being expelled. Again, this comes down to a difference in material: Metal aircrafts are easily corroded by too much moisture, whereas CFRP can withstand a higher humidity level. While you won’t notice the spike in humidity (it’s still pretty darn dry) your eyes, nose, and throat will feel less parched after the hours spent onboard

Despite their remarkable strength and light weight, CFRPs are generally not conductive like their aluminum counterparts, thus making them susceptible to lightning strike damage. Therefore, electrically conductive expanded metal foil (EMF) is added to the composite structure layup, shown in the figure below, to dissipate the high current and heat generated by a lightning strike.

I remember when AA and Delta were flying them. One of my first rides as a kid was a Delta 880(?) from MSY to DAL.
Those wing pods were an interesting add on that made them easy to distinguish from the 707 & DC8's.

While we are talking speed, did anyone in here ever get to fly on a Concorde? :
