Be careful that data doesn't say what you think it does. Southwest for example has the most MAX orders (being the launch partner for the airframe), but only uses MAX 8 and has only MAX 7/8 on order. They don't fly the MAX 9 at all.

Because of the long lead time for aircraft and financial commitment, many airlines will place large orders and take delivery of aircraft that they then turn around and sell or lease.

Is the model number relevant because 7s, 8s, and 9s have different MCAS, the system that Boeing deleted from the flight manual that contributed to the catastrophes in 2018 and 2019?

Or because the defect in engine inlets and anti-ice systems that can cause the engine housing to overheat and break off during flight, for which Boeing requested an exemption to postpone fixes, is different for each model number?

Or because each model has different pressurization systems and warning lights, that Alaska Airlines "reset" to turn off the light so they could continue to fly, instead of thoroughly investigating and resolving?

Or because not all the models have the same door plug with a loose bolt that blew out?

How much is common among all Max models, and why shouldn't the public be concerned about all variants of them?

All Max have tarnished reputation now, especially in light of this max 9 variant having this issue.

Interestingly, the sealed door only relies on a bunch of bolts to hold it against cabin pressure.

What should it use?

The model number is very relevant because MAX9 is currently grounded. If you are trying to figure out how it impacts your upcoming travel plans (seemingly the point of the original submission) then simply looking at "MAX" is not super useful.

I'm less interested in how the incident du jour affects travel plans.

I'm more interested in the continuing drumbeat of engineering failures, quality control lapses, apparent corner cutting and evasion of regulation that affect various Max models.

If I have a choice, I'll choose an airline that doesn't have any Max planes in their fleet.

The article only mentioned 737 Max. By now, I'm sure many would want the full Max list given its spotty track record.

If you want airlines that are flying 737 Max 9, there aren't many. And you can get that list here.
