They might get a great offer from Airbus as a launch operator for the A225. WN is large enough to have critical mass allowing for a second type to be efficiently operated.
Exactly. Given their size, it would be irresponsible for their management not to evaluate all options. The art of strategy is knowing when it needs to change. Just because WN has always been an "all-737" operator doesn't mean that will always be the right strategy in the future.
*AS has joined the chat*
Remember when AS proudly boasted an "all-Boeing" fleet on their planes before the VX merger brought in the A320 family?
Just because WN is an all-737 operator now, that doesn't mean they will be forever. Eventually, the reality is going to set in that a different type will be added to WN's fleet within the next 10-20 years. If nothing else, WN is doing due diligence to see what options are out there in a post-737 world.
