Doesn’t really matter for Alaska. First of all it’s going to be certified as is eventually, once the FAA is finished with their posturing and Boeing greases the appropriate skids. Second, even if Boeing decided not to go forward with it Alaska would either just change the order to Max 9s or take fewer planes, pretty simple.
A couple delusional folks over on the other Alaska forum thinking this might mean life for the Airbus at Alaska are just that, delusional.
