Well, I wasn't asking who might accept this position...or refuse it. I was asking about the structure of the offer faced by those FAA license holders who DO take it.
And I can assure you "...anyone with... widebody experience (or Boeing experience for that matter) ..." is not automatically moved to the head of the hiring line at US major. Feel free to dispute that but I know otherwise.
The Norwegian offer may in fact be a non starter for US citizens when all is said and done but it's far too early to make such a pronouncement.
I'd guess it might not take long to see how it turns out.
