Re: United Airlines in advanced talks on purchasing 100-150 737MAX

The 350 has been kicked down the road two times; rumor is it will be done a 3rd time then cancelled. By keeping it on the books it gives UA options, but over a decade has passed since the order and UA is on its 3rd administration since then. If there was a need to have the plane it would have been ...

Re: Why no 787NG still ?

As others have said, not the time yet. I think the tweaks to the 788 to achieve more commonality with the 789 and 787-10 has been a big focus and possibly helped it win additional orders with AA. Any major additional changes are probably 5-10 years away.

Re: Rumor: Used Delta Aircraft Order

Based on internal rumors and recent hints from the VP of Flight Operations, Delta could announce an aircraft order in the coming days for around 7 A350s and 27-30 used 737s. If DL has the cash on hand and the price is right, why not. As they say on wall street, buy when there's blood in the streets.
