I got an email welcoming me to my new Carnival Sea Miles credit card. I haven’t gotten the card yet. When it comes, I will transfer the balance from my current credit card (AAdvantage), and then cancel it. I will get Sea Miles for the transferred balance. Then I will pay off the balance. Way cool! I get 5000 Sea Miles just for activating the card in the first place. I take more cruises than I fly on American Airlines these days.
