I was just on an AA MD-80 on Friday and I noticed a few things: 1) Flow from my gasper vent definitely varied with engine RPM. 2) I didn't hear a lot of engine noise up in the bulkhead row of Y, but man was the slipstream loud once we got up to speed. By contrast, on approach it was almost like we ...Jump to post
Engine thrust has nothing to do with range unless you're talking about takeoffs from short runways. Really? You've never seen a flight taking off on a long runway limited by the climb limit weight, based upon obstacke clearance climbing out after V1 with an engine failure? Yes - I've done my fair s...Jump to post
The C-Series can fly transcons without breaking a sweat Delta got the small engines. I wonder how much that will shorten the range?

What would be the reason(s) for Delta to choose an engine whose performance is "restricted"? Lower price of the jets, and lower operating/maintenance costs for Delta. They don't want to pay for "too much airplane." People were amazed on the other thread that airBaltic has done 5...Jump to post
A220 if pushed, it can fly transcons, Hope to see Delta do that one day, if not use these planes (especially if they top up with the A220-300) to add second daily flights to SAL, GUA, SJO, TGU, from ATL and LAX.

It would be nice if an aviation journalist would do the research with PW and airBaltic and then provide more detail.
Sadly, no one will pursue PW, and if someone did, they probably would get a straight answer.
Is it hypothetically possible that if a potential A220-500 exists in design that DL could find good use for it? Yes and yes. Imho, this is why Boeing did their dumping claim. Fear. CS500/A220-500 will be a fantastic 149 seat aircraft when (not if) it appears. I expect Delta to order another 100-150...Jump to post
The 737NG had a completely new wingbox. If Boeing could have created a significant financial advantage by redesigning the gear to be fully enclosed, it would have done so for the NG. Instead, it consciously retained the old arrangement. Boeing did create, and then redesigned for the NG, plastic whe...Jump to post

Its interesting that the DC9/MD80/90 series, DC8, DC10/MD11, 727, 757, 767, 777, 787, A300, 310, 320, 330, 340, and 380 all have fully enclosed gear. Surely they can't all be wrong?

When the 737 was introduced, it was a short range airplane. The argument against main gear doors was that the fuel savings wqs negligible on short routes. Now, more than 50 years later, 3 major variants later, and with 3-4 hour legs routine, it still has no gear doors. It doesnt seem like such a gr...Jump to post

Back the OP question...which has the advantage?
It's not even a fair question imho, other than at extreme range. The 777LR OEW is much greater than the A350, and the engines are 10+years older on the 777LR. The 350 has a huge advantage on 90%of likely city pairs.
I personally agree that the A330Neo appears to have been a mistake order. If it had sold better I would see things better. But Delta is going to be the proud new owner of an orphan fleet. Part of me wonders if ego was a factor since Richard and crew couldn't get the 787 at the price they wanted. On...Jump to post
All just mho: At the time of the merger with NWA, the combined Delta fleet had approximately 250 757 aircraft. Since that time, about half (~123) have been retired.

Scrapping an airplane is not as simple as it sounds. For example, the elevator counterweights in the L1010 were made from depleted uranium. The fuel densitometers in the 757/767 have a radioactive material in them. Perhaps Iran lacks the technical capability to scrap them properly?Jump to post
MD88s are mostly being replaced by 321s. A220 will mostly replace 76 seat RJs. I say mostly because it isn't one for one as so many erroneously postulate.

What‘s holding BBD/Airbus back from delivering more than 1 frame per month? Is the PW engine supply chain still an issue?

What a fantastic video. The long awaited replacement for the DC9 (Delta was launch customer and first into service in 1965 IIRC) series is finally here.

Like others, I agree that the 7 days severance was an insult. And an injustice. BA management must be totally disconnected from the front line employees.
I've been reading for months about difficulties at Cathay Pacific. The HKG airline market must be a bloodbath.
Have they selected an engine? Given they're already flying PW1100G, I'd imagine that.

In service experience has been very, very good according to all that I have read. Perhaps an intense focus on quality has driven the slow ramp up and 6-8 post production flights.
