# 257.1 Purpose.

The purpose of this part is to ensure that ticket agents doing business in the United States, air carriers, and foreign air carriers tell consumers clearly when the air transportation they are buying or considering buying involves a code-sharing arrangement or a long-term wet lease, and that they disclose to consumers the transporting carrier's identity.
