that's Great! the 737-9 MAX airplane can then get on the move to Hawaii and Transcon until the 797 is ready. I would bet United retires a bunch of 757's it\f the -9Max is as good as Boeing claims. Or as good as United Hopes they are. But? Since UAL has the A321's on order? We'll now see the 737 and A321 side by side to see for ourselves.
