I heard it was an order for 200 787-8/9/10 with -10 performance enhancements. It's gonna bring wide body CA down to 2yrs and open up CLE/MMCO/LAS 787 bases.

But I'm gonna do the regular pilot thing and grouse about how it's shortsighted of us that it's not an order for 747, 767, 777X, reintroduction of the 757 line, or some weird A330/350/220 order requiring a few new types to be added. Sadly this will only be the most advanced, fuel efficient, comfortable (ok, yoke) cockpit aircraft we could lay our hands on, competitive for the next several decades, and will swap out 767s that pay like 739s for 787s that pay like 747s.

TL: DR this order will be a massive disappointment in my expert opinion
