14 CFR Part 382 Nondiscrimination on the Basis of Disability in Air Travel (Air Carrier Access Act) (with amendments issued through May 2016)

(c) As a foreign carrier, you are not subject to the requirements of this part with respect to flights between two foreign points, even with respect to flights involving code-sharing arrangements with U.S. carriers. As a U.S. carrier that participates in a code-sharing arrangement with a foreign carrier with respect to flights between two foreign points, you (as distinct from the foreign carrier) are responsible for ensuring compliance with the service provisions of subparts A through C, F through H, and K with respect to passengers traveling under your code on such a flight.

Example 1 to paragraph (c): A passenger buys a ticket from a U.S. carrier for a journey from New York to Prague. The ticket carries the U.S. carrier's code and flight number throughout the entire journey. There is a change of carrier and aircraft in Frankfurt, and a foreign carrier operates the Frankfurt-Prague segment. The foreign carrier is not subject to the provisions of Part 382 for the Frankfurt-Prague segment. However, the U.S. carrier must ensure compliance with the applicable provisions of Part 382 on the Frankfurt-Prague segment with respect to passengers flying under its code, and the Department could take enforcement action against the U.S. carrier for acts or omissions by the foreign carrier.
