Let's switch gears for a second. Pretend you are Boeing. One of your biggest customers (with hundreds of millions of dollars of future business already on the books) is the target of a hostile takeover by a carrier with huge ties to your biggest competitor.

I wouldn't necessarily rely on Boeing. The relationship between Boeing and DL has significantly soured over the past few years. DL has NOT been a good Boeing customer.
Remember when DL was crying poor to Boeing and defering aircraft deliveries, while at the same time spending billions on CRJ's that were being used to replace those Boeings. Between now and 2009, DL is only scheduled to take delivery of a whopping 15 planes from Boeing.
This might explain why Boeing has chosen to remain neutral so far. If Boeing really thought an independent DL was going to generate a significant number of orders, I'm guessing they would have already sided with DL. However, Boeing just isn't sure of that given DL's history.
While I don't think this merger is a good idea, I wouldn't count on Boeing to be DL's savior.
