When I log in to the travel site, I see my platinum card next to my name on the upper right hand corner. When I put in details of the flight I want to book, the flights come up , but my card changes to my Bonvoy card and I don't see the Platinum fares. Besides removing cards from my online account, is there any way to fix this? They do not have the same last 5 digits, and I haven't had this problem in the past booking flights.

Thanks
