Pick seats with CA-codeshare (999 ticket)
I have a CA ticket PVG-NGO-PVG with the return on NH.
I usually avoid codeshares, but this fare was the most convenient.
Anyways I called CA and got a confirmation number, but it doesn't work on the NH website, so I'm wondering if I call them will they be able to assign me or let me pick a seat? Or will a call be pointless?
Thanks!
