Delta knows if they sour the relationship with Boeing much more, it will ruin any negotiation advantage they have with Airbus. Airbus has a captive audience with Delta on anything larger than a C-Series and will price accordingly.
Let me rephrase this for you so it reflects the reality of the subject...
Delta knows that if they sour the relationship with Boeing much more, it won't matter with Airbus, no matter what, when the time comes for a large wide body order, Boeing and Airbus will both submit competitive bids
, because both manufacturers know that if they try and get to aggressive with the pricing DL will head over to the other manufacture, that is just the nature of the business.
SW like Southwest?
I highly doubt WN/Southwest is abandoning its successful single type rating model to introduce a 797.
If WN decides to get serious with international flying, I am sure they will start with routes that they can use their 737's on, but at some point they will need a more capable aircraft. What will be more interesting is the reaction of the US should WN ever decide to get into the longhaul game.
WN is great if you need a quick trip within the lower 48, but as they expand from being a niche LCC to a major domestic airline, their tiny international service and lack of codeshare options to connect outside of the lower 48 makes them a much less attractive option.
Huh ????? You do know that WN carries by FAR the highest number of domestic passengers in the US right ? Not even close, the lack of codeshare and international flights really has not stopped them in any way, as I note above, what will be interesting is if WN decides to start flying internationally in a serious way. with their domestic network, they could funnel international fliers into 2-3 hubs and dominate those routes.
Why would Boeing give DL that luxury when they've dissed Boeing for many airplanes in the past?
As above, it's pretty simple, money, Boeing is in the business of selling aircraft, if Delta (or any airline) puts out bids for 100 widebody aircraft it wouldn't matter what the past was, Boeing (and Airbus for that matter) want part of that pie.
