Introduction
Boeing is looking at a number of scenarios for its New Airplane Study (NAS) that would replace the 757 and 737, have ranges from 4,000nm-5,000nm, and carry as few passengers as 130 or as many as 240.
To cover this broad range of demands could require reverting back to the 1980s when Boeing simultaneously developed two airplanes serving very different missions, the 757 and 767, that shared cockpits and some other common elements.
Boeing faces some hard decisions in the coming years, as Airbus outflanks Boeing in the single-aisle sector with the A320neo family and its latest offering, the A321neoLR. Our analysis and sales figures show the 737 MAX falling further and further behind in market share as MAX 9 lags vis-à-vis the A321neo.
We spoke with Kourosh Hadi, director of product development at Boeing, during a break at a conference last week organized by the British American Business Council-Pacific Northwest, and covered this and a number of other topics.
Summary
- Boeing is studying a New Light Twin (NLT) and New Single Aisle (NSA) to replace the 757 and 737 airplanes.
- The tipping point between an efficient NSA and the NLT is around the passenger size of the 757-200.
- Boeing is evaluating materials, including metals and composites, for the NAS and the manufacturing process, which will also be a determining factor in the materials for the new airplane.
- Engine advances for the 777X’s GE9X are beyond the GEnx and CFM LEAP of today and could help drive the next new small engine technology.
- Although having a miniscule portion of the 100-150 seat market, Boeing today plans to continue participation in at least the 130 or 150 seat sector even as airplane size moves up every year.

With the EIS of the Airbus A320NEO and Boeng 737MAX around the corner, we are always asked about our thoughts on the Last-Off-The-Line aircraft and how they will depreciate vs the existing fleet. Based on these requests, we have looked at a few aircraft to see how they depreciated over the last 10-15 years. CV compared a 1999 Boeing 737-400 vs a 1999 737-800 as well as a 2004 Boeing 757-200 vs a 2004 Airbus A321-200. We felt the 757 would be an interesting aircraft to review as there really has not been a direct replacement for the aircraft as of yet.
As you will see from the chart below, the last 737-400 depreciated at a much faster pace than the 737-800. For the 737-400, the average year over year depreciation rate was around 12%. For the 737-800, the year over year depreciate rate has been 5.5% which is more in line with normal deprecation expectations. For the 757-200, the average annual depreciation rate was around 8.5% vs 5.5% for the Airbus A321-200 over the last 10 years.
Odds and Ends: A350 batteries; A350 V 1.0; Southwest schedule
A350 batteries: Flight Global has a detailed story about the Airbus approach to lithium-ion batteries in the A350. The approach is more conservative than Boeing’s for the 787.
A350 Version 1.0: A blog called A350 XWB News has a retrospective on the A350’s original proposal (which we call Version 1.0, because the design went through so many iterations). It’s got the original brochure reproduced. It’s an interesting recollection, and one to compare with the A330neo. Boeing dismisses the A330neo as A350 V 1.0, but it’s really not when you compare.
A350 Final version: A350 XWB production is tracking to plan, first A350 after Qatar’s initial 8 (MSN6 to 13), MSN14 to Vietnam Airlines is going to ground tests (Station 30) after getting wings and empennage in Station 40 at the Airbus Final Assembly Line (FAL) in Tolouse. We are following this program carefully since start and the roll out of the latest XWB from wing join was within days of our prediction 6 months ago, thereby the A350 ramp to three FAL starts by end of year is tracking so far.
A380 downed by mops: Aviation Week has the story on how Qantas cleaners got the water flowing in their A380s when it should not. The incident is old (80 gallons of water flowing around in the fittings of the A380 when climbing out of LAX to Melbourne, first time in June) but one has now found the cause; the cleaners mops were getting the water couplings in a galley unlatched. Small things having big impact.
Boeing record: Qatar airways took delivery of three 787 and one 777 in one day this week; here the Flightglobal version of the Boeing announcement. Airline CEO Al Baker says ““Never in the history of an airline have so many aircraft been taken in just one day.”
Southwest schedule: Southwest Airlines adjusted its schedule two months ago to improve its on-time performance, and revealed that the new times are working.
Southwest, once boasting of being #1, 2 or 3 in on-time ratings among US major carriers, saw a steady decline in recent years as it ramped up service in congested airports, expanded in regions that were more prone to weather delays, added larger airplanes (the Boeing 737-800) to its schedule. After acquiring AirTran, Southwest tightened the schedule in an effort to cut turn-times. But AirTran’s traditional hub operation vs WN’s largely point-to-point didn’t lend itself to the tighter turns Southwest scheduled. It didn’t take a lot of insight to understand why delays were showing up on the AirTran fleet. Southwest’s OT performance is still not where it once was–it’s currently at 78.9% when it used to run in the 80s–but it’s better.
BABC Conference, Part 1: WA State’s position, Boeing’s outlook
The British American Business Council-Pacific Northwest is sponsoring a conference today on the Advanced Technologies for Next Generation Aircraft in Seattle. We’ll have several reports, starting with this one.
Alex Pietsch of the Governor’s Office of Aerospace, kicked off the conference, saying that Boeing employees more than Microsoft, Starbucks and Amazon combined.
“No one should question Wasnhington’s place in aircraft production,” Pietsch said, noting the siting of the 777X assembly and wing production, a rate increase to 52/mo for the 737 and expansion by suppliers.
Thanks to the 777X, Washington will be the only location in the US where composite wings are built, Pietsch said.
Kourosh Hadi senior director of Boeing Airplane Product Development, said that trends in commercial aviation during the next 20 years indicate that single-aisle aircraft and demand remains the “fastest growing, most dynamic segment” in the industry. Traffic demand continues at 4%-5% per year, despite four recessions, two financial recessions, two Gulf Wars and other global factors.
Hadi indicated that “advanced designs” fall within the 2021-2030 timeframe and “future concepts” fall from 2031 and beyond. Advanced designs include advancements in aerodynamics, systems and propulsion. Future designs might include SST and other concepts.
Technology has to add value, Hadi says, for performance, cost, production rates, Cash Airplane Related Operating Costs (CAROC, a common Boeing term) and environmental issues are focus areas.
First flight of the 737-8 MAX is early 2016, with EIS with Southwest Airlines in July 2017.
Hadi said it was “mind-boggling” that Boeing is improving the 777 by 20% with the 777X, a plane he characterized as one of the finest aircraft ever produced.
Flight test of the 777X is slated to begin in 2019, with firm configuration next year and detailed design in 2016 and the production to begin in 2017.
- Our observation: Hadi detailed the 777 Classic, 777X and 787 families but only talked about the 737-8. FWIW.
- In a change from practice, and a refreshing one, Boeing compared its next round of aircraft with its own current and past generation aircraft rather than bashing Airbus at every opportunity.
Delta’s wide-body fleet plan: could it include used 777-200ERs?
Delta Air Lines is supposed to make a decision on its Request for Proposals for 50 wide-body aircraft before the end of this year, perhaps as early as next month. The competition is hot between the Airbus A330-900, the A350-900 and the Boeing 787-9.
Delta is understood to use the aircraft to beef up its growing Seattle hub across the Pacific; for its Detroit hub, also to Asia; and its New York JFK trans-Atlantic hub.
In addition, Delta is phasing out the last 14 of its Boeing 747-400s inherited from its merger with Northwest Airlines by the end of next year.
The A330-900 is viewed as a trans-Atlantic airplane, while the others are viewed as largely, but not necessarily solely, trans-Pacific aircraft, according to our information.
But there could be another wrinkle. On Delta’s third quarter earnings call, CEO Richard Anderson made some intriguing comments that could raise another possibility: acquisition of used Boeing 777-200ERs.
To put this in context, recall that Anderson and Delta actively seek out inexpensive used aircraft which, while hardly competitive at high fuel prices when comparing operating costs vs new aircraft, provide low capital acquisition costs and low ownership costs.
Here’s the exchange on the earnings call, as recorded by Seeking Alpha’s transcript:
Oct. 28, 2009: five years ago today, Boeing announced 787 Line 2 goes to Charleston; then, now and the future
This is about eight pages when printed.
It was five years ago today that Boeing announced it would locate the second assembly line for the 787 in Charleston (SC).
The decision was expected and, some say, had actually been made months before–as early as the preceding February. We take a look back at the events leading up to Boeing’s decision to put the second line in Charleston, what’s happened since then and where Boeing will be in five more years.
CASM Paradigm: Lower Seat Mile Cost or Higher Yield; Evaluating the GOL competition
Subscription Required
Introduction
As Brazil’s budget airline GOL reportedly evaluates whether to acquire 20 Boeing 737-7s or Embraer E-195 E2s, the principal of the “CASM Paradigm” is a concept worth examining.
This head-to-head evaluation of the E-195 E2 and the 737-7 MAX is a rarity. Typically the head-to-head involves the Bombardier CS300 and the Airbus A319neo. All three have the same seating capacities. The E-195 E2 has slightly fewer passengers than the 737-7 with similar seat pitch.
The competition is also what might be seen as a contrary competition. Airframers agree: the airline industry is upgauging. Capacity discipline, long elusive until after the global financial collapse of 2008, has been driving load factors higher. But lowering unit costs, or the Cost per Available Seat Miles (CASM) has long been the principal measure by which airlines, OEMs and aerospace analysts measure efficiency.
Although Trip Costs of aircraft operating over a route is important, the trend toward upgauging at all levels clearly is the driving force.
Figure 1. It’s an age-old debate: the cost per available seat mile (CASM) vs trip cost. CASM typically wins, and the airline industry is migrating toward larger aircraft. Embraer, not surprisingly, thinks this has gone too far. Graphic: Embraer, reprinted with permission. Click on image to enlarge.
Embraer takes a different view, arguing that trip costs and a smaller airplane should trump the CASM obsession. A smaller airplane will mean higher yields, EMB says. A larger airplane provides lower trip costs but drives yield lower.
We visited Embraer’s headquarters earlier this month and received a full briefing on what EMB calls the CASM Paradigm. In our report today, we detail the presentation and discuss other considerations beside CASM vs Trip Costs that drive the size of the aircraft acquired.
Summary
- The CASM Paradigm becomes a vicious, circular cycle, driving airlines to larger aircraft but lower yields.
- Extra seats on larger aircraft mean lower unit costs but at the cost of profits.
- Scope Clauses remain an issue in the US.
- Connecting traffic, pay scales also are issues.
- We analyze the operating costs of the E-195 E2 vs the 737-7.
- We discuss the GOL competition.

Part 3 of 3
Introduction
In Part 2 of our three-part 757 Replacement analysis, we took a close look at Airbus’ new 97 tonne take-off weight A321neo, revealed in a world exclusive by
Leeham News and Comment October 21. We analyzed the A321neoLR’s capabilities and limitations when compared to Boeing 757-200W and we saw that it could do the international flights that the 757-200 does with about 25% better efficiency. In this final Part 3, we will now compare the 757 and A321neoLR against what can be Boeing’s reaction, a clean sheet New Single Aisle, NSA, or New Light Twin Aisle, (NLT). First the conclusions from Part 2:
