49 U.S.C. § 41507 — Authority of the Secretary of Transportation to change prices, classifications, rules, and practices for foreign air transportation

(a) Fixing discrimination. If the Secretary of Transportation decides a price an air carrier or foreign air carrier charges or receives for foreign air transportation — or a classification, rule, or practice affecting that price or the transportation's value — is or will be unreasonably discriminatory, the Secretary may (1) change the price, classification, rule, or practice to fix the discrimination, and (2) order the carrier to stop charging or collecting the discriminatory price or using the discriminatory classification, rule, or practice. (b) How the Secretary can act. The Secretary may act under this section on the Secretary's own initiative or on a complaint, but only after notice and a chance for a hearing.
