MAX 10...sufficient 757 replacement? (real world)
Haven't seen the details but I'd expect it to be too low to the ground to take on the size engines it needs to gain the range of a 757. Engines will also be a limiting factor regardless as a next generation engine has not been developed at the 757s thrust ballpark...

Well, Boeing just officially launched it today so you might want to take a look at it....They do have changed the landing gear. And 757 thrust is not necessary as its capacity is just around 321neo's capacity
No it won't replace.
The point of the 757, and the reason airlines miss it is it has the ability to do 500 miles segments and 3000 mile segments profitably. High density short haul and long, thin US-EU.
The 737 Max and the 321 Neo can't do that. They'll do the short stuff more profitably for sure. And yes they have the capacity, and the theoretical range. But a theoretical range isn't much use in winter with super-strong headwinds. The Max is an effort to stem the tide of the 321LR, which is also inadequate (but slightly less so). But a 757 replacement it will never me, no matter how much Airbus and Boeing trying to dress up their frames.

For the purpose of AWS, 321LR would be a closer match because of the advertised range... regardless of their actual capacity.
And in AWS, the advertised range of A321LR would be enough to cover basically all 757 segments
If they one day to the MC21-400, it might do the job. It's a single-aisle too, but broader than 737s or 321s, which is good for comfort on such long flights. But they're far from doing it for now, AFAIK, and they'd probably need an enhanced engine.

Well, the effect of aisle width to passenger comfort is not modelled in AWS.... (And I think the aisle width of 757 is actually narrower than 320?
My thoughts are no it isnt..but its not supposed to be the more I read about it. Its main missions will be transcon and hub to hub. The 797 will the one to watch.
