An agent at LGA suggested I try checking in w a Canadian PP# which I have. Tried it just now and again, checked in but must see agent/kiosk for actual boarding pass. Frustrating!
Yeah, a few people mentioned it was passport vs NEXUS, but I've tried everything, and it makes no difference. If it doesn't work, it doesn't work. If it works, it works.
