I asked Alan a direct question about the 787's in late December. His response was that his priority was to pay down debt.
I don't expect any announcement on a new type soon.
A colleague asked Joyce a few weeks ago about the 789. His words" we can't afford not to get them".
I personally asked AJ recently: "Can you please tell me how many 787's you are ordering so I can post it on PPRuNe?"
To my surprise, he told me exactly how many airframes, when they'll be delivered, what routes they will fly, by whom and on what contract.
But I've changed my mind, I'm not going to post it here. So you'll just have to wait...
