No carrier may impose any contract of carriage provision containing a choice-of-forum clause that attempts to preclude a passenger, or a person who purchases a ticket for air transportation on behalf of a passenger, from bringing a claim against a carrier in any court of competent jurisdiction, including a court within the jurisdiction of that passenger's residence in the United States (provided that the carrier does business within that jurisdiction).
