Yes, the credit card gets charged when the accumulated charges on the KTTW card less any OBC, applied gift cards, etc. exceed a pre-set threshold. Usually, we have not reached that level except on longer transatlantic or Panama Canal cruises. On our first Panama Canal cruise in fall 2017, the credit card was charged when we hit $850. On the transatlantic in May 2018, we got the first cc charge at $1000. For our most recent Panama Canal cruise this year, I prepaid $500 plus had a $200 OBC, so we didn’t get any charges to the credit card until the end of the cruise, since these were below whatever threshold was being used. On our 7-night and shorter cruises, we usually just see a single credit card post at the end of the cruise. Over 17 cruises, we seem to spend about $100 per day on average each time. Whenever I think we’ll get by for less, DW seems to find something that pushes us back up to that level. How she manages that I’ll never know
