UAL warned Boeing a couple of months ago about the NMA. Either launch it or we go Airbus 321XLR's. Then that week Boeing delayed the NMA yet again.
If Boeing doesn't get their act together with the NMA, they are conceding that segment of the market for a very long time.
I wouldn't be surprised it we, UAL, reduce or cancel our Max 10 orders. That airplane is an abomination--in favor of more 321's, about the time our A350's are due? What is it now, 2027?
