Just booked a 14-day cruise for Feb 2024. I asked my TA to book it through the Princess Plus package and see if Princess will upgrade it to the Princess Premium. When my TA confirmed the reservation, I asked her if Princess upgraded us to the Premium package. The TA stated, "it was put on your booking because you had the offer as a veteran" and also the $250 OBC. Apparently, according to my TA, Princess sent out the offer to all their Military Benefit cruisers. Since there was no expiration date, I hoping this will be a permanent benefit.
