The travel agency would be the one who makes the charge. Why not call the credit card company today, and see if it has indeed been charged. What sometimes happens is a ta will give you one date, which, is in fact, a few days before the actual payment is due, just to be safe.
Don't panic if your ccc says it does not show the chatge, just contact your ta bright and early, so you can put your mind at ease.
Trip, with her book & tea!
