I find it hard to believe we'd order 100 737-900s right now.
Its not a good long-term plan, and that's a lot of money tied up in replacing an existing capability. Even worse would be a committal to buy the 737-9 with the LEAP-X engines.
It's possible DAL is using the 787 penalty to get these jets for a song, right at a time when Boeing need orders for its cash cow that's about to run dry...
Airbus vs Boeing is as childish as Ford vs Chevy does it really make a difference?
Now if we're talking MB vs BMW, now you're talking
