So WN's order for 200 MAX's trumped the desires of the remaining 2600 orders from other airlines?
No way.
That argument
may have been valid for the NG, but not the MAX.
The MAX was destined for minimal change due to market pressure. The NEO is a year ahead of it, and Boeing needed to get something to market asap.
