I booked online four weeks ago, direct with P&O, for a trip in October 2023. I didn’t think at the time to check Blue Light or Defence Discount - I have both. I rang yesterday and was told the Blue Light discount had to be done at time of booking, by ringing P&O. However, the Defence Discount could be applied there and then. I just had to give my membership number. I had a new email in a matter of minutes confirming the new OBC. I rang about 6pm and waited about 7 minutes to get through. You can’t have both discounts applied at the same time, but the amounts are the same for each. Just depends on duration of trip and cabin selection.The P&O agent was really helpful.
