Yep, usually gotta call, shouldn't take too long.
That said, on a similar note...I'm having a harder time lately getting anywhere with the other airline bookings. Booked a couple flights via UA, I love that their site offers the other airline codes (or some of them, doesn't seem to offer ANA codes) but then I punched them in on the AC site and wasn't allowed to do anything in the booking, including seat selection.
