Simple Flying: Why Boeing Can't Stretch the 737 Max any Longer

Simply Flying online magazine has a number of articles, including the article above, that are easy to read and contain a lot of historical and background information.

I was kind of surprised that the upcoming MAX-10 has way more orders than MAX-9. Apparently the economics of the MAX-9 can’t touch the 321NEO, but the MAX-10 gets close.

Boeing claims the MAX-10 provides the “lowest cost per seat of any single-aisle airplane.”

737Max can be stretched….. it’s called the 797. J/K.

Yes, A321neo is very efficient and been on them many times for long haul flights.

Love to read it.

I looked at something similar a year ago.

It was a fascinating read encompassing many design choices one being the original design was very low to not require specialized loaning and unloading equipment. Not completely enclosing the gear when retracted was another , to being limited by height to be able to add more power which required an even larger diameter engine, but lots of things are easier to get to and reach for maintenance as they are low, so just tons of interesting compromises all round.Id imagine they could stiffen the wing box but maybe not.

Have to be very careful in comparing the brochure operating costs of direct competitor aircraft.
Depending upon mission and load selected either of these airplanes can come out as the clear winner.
Getting the ultimate efficiency out of the Airbus also requires selection of the Pratt GTF engine.
At least a few carriers are kicking themselves for having made that choice at the moment.

With Pratt PurePower perhaps, but it's been noted that they have problems with reliability.

AA bought Leap-X on all their NEOs even though it uses somewhat more fuel, from what I understand.

Not sure what UA is doing on the A321XLR. They've also bought a lot of -10Max, but, different missions most likely. The 321XLR is understood to be the 757 replacement by the AvGeek community, for the real answer, you'd have to know someone in fleet planning at UA.

The OEW of the Boeing is lighter than the Airbus, so at shorter stage lengths it is more efficient. The advantage eventually flips to the bigger fan of the Airbus and the longer the flight, the more the gap widens.

The 321 XLR is the planned 757 fleet replacement. It’s been public for a long time.

What is also public - Airbus has failed to deliver the airplane.

It’s several years late. So, it’s pretty hard to replace an airplane in your hands with a promise that has yet to be delivered.
