The NEO is simply a better aeroplane than the max. The 900 can't compete with the A321.
I'd be shocked if Qantas didn't get some.
The 737 is a lovely aeroplane and the Ng wing is a better wing than the 320, but it's an old aeroplane design and no matter how good the wing is, it's still attached to a 1960s fuselage. It's basically a B707!
