No waitlist for 2nd leg: EWR-HND-SGN
I am trying to apply pluspoint on my upcoming trip: EWR-HND-SGN (booked through united.com). Called 1K hotline and got the 2nd leg (HND-SGN) flipped to native NH # from codeshare. I see the option to waitlist the 1st leg but there is no even waitlist option for the 2nd leg. This is my first time ever to upgrade NH flight using pluspoint. Any idea what I did wrong? It's class U for both legs, btw.
