In the past I've been able to successfully modify/refare an onboard booking by modifying the reservation, changing itinerary, and before confirming the change modifying the reservation to the itinerary I want. Now I'm seeing a price drop on the 11C for one of my cruises and it's not reflecting the refare no matter what I do. I tried using the reservation I want to modify and I tried going into it with a dummy reservation I have. It's still not working. The OBB can have date/itinerary changes, right? I know it will fall under the new OBC levels, but I thought the 10% discount remained.
