Ok, so to be clear - you purchase a Flex fare and within 24 hours you call and upfare to P fare. In this case I would assume that you can cancel for no penalty with a full refund.
But I don't think I would even bother getting on the phone - I would just cancel the original fare and purchase the P fare.
