I recently contacted Carnival to request my shareholder benefit to be applied to my upcoming cruise on Azura in September but received an email back to say that my application was denied due to "the promotions applied to your booking are non combinable with shareholder benefits, you have been given a net rate discount through your travel agent therefore with this promotion given its not combinable" The cruise was booked through the TA I have used for the last 14 years, I asked for a quote for a stay and cruise on the Azura and was happy with the price so booked it. I didn't get any OBC so not sure what Carnival are saying? Anybody else experienced this?
