A hold on your credit card typically will only last a few days; however, it can remain on your account for up to 31 days. While the hold is in place, your available credit on your credit card is reduced by this amount until it is released. A frequent traveler staying in a new hotel every night could find they have no credit available on their credit card because each hotel, rental car, etc., has placed holds on their card, using up all their available credit.
