How about this then. Name an airline that has both A220 and A320 in service. What is the seat configuration they have for A220 and A320, what is the relative CASK or CASM?

Easy. Air Canada, and that's just off the top of my head. Literally worked with their books when I worked at SeaTac airport.

But your question is actually a trap, because a specific airline's CASM is not how individual airlines determine new aircraft acquisition. CASM in general is a metric that's much better at assessing the commercial value of existing and prospective routes. It can also serve as a valuable tool to determine whether to order more airplanes of the same type, or as a baseline comparison for acquisition of new aircraft types.

The fundamental questions you should be asking, is if the A220 and A320 market segmentation overlaps, if they do, how do their cost curves (curves not case-by-case fixed numbers like you are asking for) compare, and if they do, which aircraft is better?

I see, can you name some airlines where this would make sense? Is this NMA going to be twin-aisle? What kind of range are you looking at?

Singapore, Qantas, Thai Airways. The NMA needs to have a capacity of 220+, possibly up to or beyond 260. The range should be at least 4,500, with a possible variant looking at beyond 5,500 though I don't believe there is large demand for ranges beyond 4,500. The NMA needs to be a people hauler that can take people medium-long distances.

The details of how that's done is for the engineers to figure out, but there is a need for such a plane. There is a reason why the A321XLR is not more successful. A ground-up airframe is likely needed to address this market segment. There are definitely prospective routes that can be opened up in the West for such a plane, and considering the dynamics in Asia, the need for such a plane is likely even greater.

I can definitely name two pretty large airlines that wants A220-500 as replacement for A320CEO. In fact, it has not ordered any A32NEO because it is waiting on A220-500.

In fact, one of the many fears of A220-500 is the possibility of cannibalizing A320NEO

And there are definitely airlines that could benefit from a slightly bigger A220-500, but we have to look at why they want such a plane, and whether we can extrapolate it to the market at large.

But anyway, if we want to discuss whether the A220-500 should exist, we shouldn't be looking at which airlines want it. We should be looking at air routes, not airlines.

A220 is not a replacement for the A320 because it is just too expensive and too inefficient to manufacture. They have had years to solve the issues with it and so far managed to achieve little in mitigating these issues. It also has had terrible issues with the Pratt & Whitney geared turbofan engines it uses.

I thought the shortened 787 was meant to service this market?

787 serves longer range routes. For the purpose of NMA it has too much range and too high operating costs.

There is certainly a business case to make against an NMA type plan from existing at all, but I don't find them particularly believable. Anyway, much like defense discussion, discussion regarding airline economics can be completely idiotic. The conversation shouldn't just be around operating costs, but also about route planning and operations in general. There is a lot of nuance involved in these things.

I know a lot less about the commercial aviation manufacturing industry, than about the airline industry. But in my experience, 99% of debate is centered around airliner manufacturing that bleeds into airline operations, instead of the other way around.

Yeah the GTF is terrible and is literally bankrupting airlines.

COMAC was smart to choose the technically more conservative LEAP engine for the C919.

Both engines have had their problems. You're presumably talking about Go First where supply chain issues compounded the GTF's technical faults, but on the latter CFM are themselves in the midst of testing new blades to address durability issues in the dust of India and the Middle East.

Basically none of the engine OEMs are rolling out a rock-solid offering at the moment, even if GE seem better on that front than most. Main lesson to be learnt here is that AECC needs to do a metric ton of flight testing around the Gobi with the CJ-1000A

wow, AC. They must know the answer with that humongous A320NEO order that they made. Oh wait, they never made one. They picked MAX over NEO and only picked XLR because they need a plane like that for TATL markets

I can assure that A220 can serve every route that A320 can serve and serve them better.

I will give you an example, A220 has now been put on BOS-SJC by B6. That's a route they served for many years with A320CEO. Guess what, it just can't make the westbound fly a lot of the times in the winter due to strong wind. Not a problem with A220-300.

A220-300 CASM is a lot lower than A320CEO despite 22 fewer seat

Let's see, DL topped up their A220 order book multiple times
So did Jetblue
So did AirBaltic

Pretty big endorsement all the way around.

lol, A321XLR already has over 500 orders before it joined service

that with minimal investment from Airbus. On top of getting additional orders, it incentivizes airlines to order more A321NEO. XLR is a huge winner. Airbus is charging a nice premium on every XLR it sells, because it knows it has a winner on the hand.

There is a reason why I asked you what NMA looks like. Boeing struggled for a long time before giving up on the project because the market size is 4000-5000. Sounds like a lot, except it knows XLR would get a huge fraction of that. More importantly, NMA could never achieve cost advantage vs XLR due to the fact that it has 2 aisles instead of 1. It can't fit in your standard 737/320 sized gates. And it could not achieve fleet flexibility due to the fact that it would not have cost advantage over A321NEO for short routes.

You don't need to have 2 separate seniority lists, support staff and a bunch of other things when introducing XLR on top of your existing A320 fleet. You do have to do that when adding a NMA.

So, let's go by your example, how is TG going to compete against AirAsia on sub 5 hour flights with a twin-aisle aircraft against single aisle aircraft?

As for SG, how many routes out there would you rather have NMA sized aircraft over 787/350 or 737s? Is that going to be large enough to warrant an order?

Again, Boeing looked at this and realized that not many airlines want a separate fleet type for something that can be done by A321 on the bottom and 787 over the top. So it didn't go for it.

Now, if you look at COMAC's business case, it gets even weaker. the largest market needing something like NMA is for TATL airlines, which they don't have access to. So, what's their business case?

On the topic of the C919, is there any commentary out there on flight deck ergonomics vis-a-vis the duopoly? Curious if the necessary type rating training also comes with some quality of life improvements for the pilots
btw, airlines don't cares about this
Air France and JetBlue? Or are these Chinese airlines?
there we go, AF and B6 are major ones.
Right now, B6 has need for replacing over 100 A320CEOs. It's economics are horrible by today's standard. It has resisted ordering A320NEO for a reason.

The current NEO lineup is optimized around A321NEO. That's what everyone is getting now. It's only taken this long to launch A220-500 because concerns of cannabilization. However, it's going to move beyond that when enough airlines are banging on the table.

Airbus's case of A320 vs A220 is exactly what COMAC needs to be looking at. C919 will slowly get upsized until it can fly with HD variants of 240 seats. You can't downsize C919 for sub 160 seat market, because it's not optimal. So, you need to have an aircraft optimized for about 120 seat in 2-class layout that can have a stretched version of about 150 seat in HD layout.

You mean 787-3? There is a reason it didn't sell in the market.

Yeah the GTF is terrible and is literally bankrupting airlines.

I mean longer term, GTF is the more efficient engine. It just has more room to grow.

Okay? That's not a win for the A220 lmao. You asked and I told you. They're not like for like replacement. The A220 is not going to replace the A320 family.

I can assure that A220 can serve every route that A320 can serve and serve them better.

No you can't, because they're not like for like replacements. You might as well tell every airline to stop buying any A320s or A737s, but you can't. Airlines determine aircraft acquisitions based on route operational costs, not one aggregated number.

I will give you an example, A220 has now been put on BOS-SJC by B6. That's a route they served for many years with A320CEO. Guess what, it just can't make the westbound fly a lot of the times in the winter due to strong wind. Not a problem with A220-300.

I hope the AirBaltic "endorsement" as proof that the A220 will replace the A320 is a joke.

Ah yes, it's really opening all these new long haul narrowbody routes for airlines and redefining the industry, that's why it's being bought in droves. Obviously not. The A321XLR is an attractive option because it's an A320 with more range. That's it. That's why all A321 versions are successful. It is a plane that fits neatly into existing operations with minimal fuss and simply gives the airline more options.

These airlines are not getting the A321 XLR specifically because they fly tons of long-haul narrow body routes over 4,000 miles. They're getting these planes because they're A320s that can fly these routes if they need to.

It can't fit in your standard 737/320 sized gates. And it could not achieve fleet flexibility due to the fact that it would not have cost advantage over A321NEO for short routes.

The A321 XLR is not a true NMA aircraft. It does not fundamentally change airline operations. An NMA aircraft would actually give airlines new options. So no, the A321 XLR is unlikely to get a huge fraction of that market.

I mean you could use the XLR for NMA routes, it'd just be... inefficient, because it's simply smaller.

And we all know why Boeing gave up on the NMA I don't know why you think it's because the business case is not viable. Boeing gave up because Boeing does not have the resources at the moment.

You don't need to have 2 separate seniority lists, support staff and a bunch of other things when introducing XLR on top of your existing A320 fleet. You do have to do that when adding a NMA.

Now, if you look at COMAC's business case, it gets even weaker. the largest market needing something like NMA is for TATL airlines, which they don't have access to. So, what's their business case?

The NMA wouldn't be able to efficiently fly routes like Bangkok-Auckland or Bangkok-Peking. Because,

A. Either these routes are too far
B. These routes are better utilized by true widebodies.

The NMA is designed for the crossatlantic market. It would create entirely new routes like Newark-Berlin which cannot be properly serviced by smaller capacity narrowbodies like the A321XLR. It can fly low-capacity flights that A350s, A330s, or 787s would be wasted on, while also being able to efficiently serve some narrowbody routes. Of course this is again, down to the specific operational requirements of individual airlines.

Though to demonstrate, I mean if you think that Qantas would rather run a diverse fleet of various A321XLRs, 777, A330s, and A350 and god knows what else, instead of having fewer airplane types that can handle capacity better and more flexibly, than sure. I suppose the NMA really is pointless.

But no, for the case of Thai Airways, this is an airline that could desperately use the NMA to consolidate its fleet into owning fewer aircraft rather than more. But I find that airline to be a train-wreck anyway. A perfect plane wouldn't save them from themselves.

You mean 787-3? There is a reason it didn't sell in the market.
Yeah. I mostly brought it up because while reading your back and forth I remembered one of the reasons for not developing NMA was because Boeing thought 787-3 could service that market without additional development cost on their side.

Captain
A small request, I enjoyed reading all above postings by tphuang, HighGround, latenlazy and others, can we have occassional full description included in your postings for all those civil aviation technical abbreviations like NMA, CASM, TG, TATL etc.

It will make our reading of your postings more enjoyable.
