Odds and Ends: Supply chain demands; Southwest hints?; Retrospective on A320/737 replacements
Supply chain demands: Earlier this week, we talked about the prospect of production wars as Airbus and Boeing ramp up over the next five years, combined with the new entrants and the new offerings from Bombardier and Embraer.
We noted that this will mean opportunity and risk for the supply chain. Ryan Murphy from Salem Partners has a long analysis the starts with the finishing sector but which goes beyond this to discuss the broader implications. It makes for an interesting read.
Southwest: Hints of things to come? Yesterday we wrote about Southwest Airlines and the demise of the Wright Amendment that restricts travel from Dallas Love Field. We suggested several routes that Southwest would launch from Love once the Amendment passes into history.
Here’s a display Southwest erected on its countdown to the end of the Wright Amendment. We think it hints at things to come. Going clockwise: Chicago, New York and Charlotte seem to be where the airplanes are going. Then Los Angeles and Salt Lake City seem to be implied destinations. But the last one? Boise, or some other obscure city?
Or are we reading too much into the placement of these airplanes?

Our thoughts:
Retrospective: We were looking at previous posts for some specific information and in the process re-read one about replacing the Airbus A320 and Boeing 737. The post dates from 2009. In light of subsequent events, it makes for interesting re-reading. We discuss the internal views of Airbus and Boeing about replacement or re-engining their aircraft and the engines from Pratt & Whitney and GE Aviation/CFM. We also touch on Boeing leaning toward not replacing the 777.
Retrospective, Part 2: Airchive has a nice set of historical looks at the development of the Boeing factory at Everett: Part One and Part Two.
737 MAX may share NG improvements still to come, which might include more seats
Boeing’s 737 MAX, still weeks away from design configuration freeze and still with lots of detailed design to come, may share improvements still to come on the current 737 NG.
The head of the MAX program, Keith Leverkuhn, vice president and general manager, wouldn’t confirm or deny a report by Aspire Aviation that the MAX family will have 6-9 more seats through interior changes, the use of slim line seats and door changes when asked during Boeing’s MAX briefing yesterday with an international crowd of journalists.
Citing unidentified Boeing sources, Aspire reported:
- Boeing to modify 737 MAX 8 doors to add around 9 seats;
- 737 MAX 8 to meet 13% fuel burn reduction per seat target after door modification;
- Door modification has negligible impact on MEW; and
- 737 MAX 7 & MAX 9 also likely to have around 9 more seats.
Leverkuhn told the media that Boeing was satisfied with the current configuration of the airframe of the NG and MAX shares this configuration. Although Leverkuhn said Boeing had no intentions of changing, it still would talk with customers–leading to the obvious conclusion that Boeing wasn’t saying a firm “no” to the possibility.
We talked with him a few minutes alone later in which he clarified his earlier comments. Leverkuhn told us that while there will be no changes to the doors on the MAX which would allow more seats, the NG program is considering interior configurations that could lead to more seats and the MAX and NG programs closely follow developments and determine what can be shared between NG improvements still to come and the final MAX design.
Airbus in January announced a space-flex program that includes two new doors, enabling high density capacity to grow to 236 from 220. Airbus previously began offering a revised aft galley/lav combination in the A320 to permit three more seats, to 153 in two-classes. Boeing has been studying similar changes, according to our market intelligence.
Sizing up engine market share on the A320 family
While competition between Airbus and Boeing snares nearly all the headlines and all the “sex,” competition for engine orders is less sexy and receives less attention.
Part of this is because of the increasing trend toward sole-sourcing. The Boeing 737 has been sole-sourced by CFM International since the creation of what is now called the Classic series: the 737-300/400/500. Pratt & Whitney believed at the time Boeing was upgrading the 737-200 that airplanes were up-gauging and bet its future on the Boeing 757 size. It was one of the classic corporate blunders of all time.
Shut out of the 737, P&W joined with Rolls-Royce and MTU to build the International Aero Engine V2500 for the Airbus A320 family. IAE came to the table late, giving CFM a solid head start on the program with a variant of the CFM 56 that powers the 737 Classic and later the 737 NG.
IAE trails to this day, but has done a remarkable job of coming from behind. CFM tends to be favored on the A319 and A320 while IAE is the preferred engine on the larger A321. IAE offers more thrust and better economics on the A321 while the CFM has better economics for the smaller Airbuses. CFM’s reliability is legendary and tends to be better than the V2500.
The blog PDXlight has done a marvelous job of dissecting the engine market share of the A320 family for the New Engine Option. We asked PDXlight to do the same exclusively for us for the A320ceo family. The results are below the jump.
