What's funny is how everyone thought no max's ever. Even today, "no max 7 or 10 ever." Even the article hints of it. Fast forward to today and their are 1200 max's flying around. If no max 7, then you have no choice. But until Boeing says otherwise, management will pull whatever levers they need to. That's why they are called managers. 99% of the 7 is done. It was used for RTS. The FAA, by act of congress, changed the rules. So now they will have to jump a couple of more hurdles.
Spending billions when you don't need to is not a good, especially when they believe(SWA and Boeing) that the airplane will come. SWA did file a S-3 registration last month to raise debt if they choose to. So they are thinking about it. I just think right or wrong, they think the airplane will come.
