Yes, while you can see upgradeability online (NF/NC) but to be certain it is best to do with a phone agent.
Booking on the phone will cost $$$ so if you see upgrade availability online and book "free" online but call and it is not available -- use the 24 hour cancel for free.
Another approach is to set up the booking online, pause just before booking and call to check availability. Hold off booking until the agent confirms availability.
