A year or two back, about this time of year, some double bonus point itineraries were offered. I had two sailings booked that should qualify. I called and asked them to add it to them. They said "sure, done," but the invoices they sent failed to reflect the bonus point offer. These two bookings were a B2B where I could cancel and rebook the second leg but the first leg had reverted to "guarantee," and I wanted to be able to book the same rooms. I did a full cancel on the second leg (with deposit refund) and immediately rebooked it into the same room (pricing had not changed). The invoice showed the promo. I ultimately sailed and, with no surprise, earned the bonus points on the second leg but not on the first. That's one recent data point. Take it for what it is worth.
