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

(a) As a carrier, you must provide or ensure the provision of assistance requested by or on behalf of a passenger with a disability, or offered by carrier or airport operator personnel and accepted by a passenger with a disability, in transportation between gates to make a connection to another flight. If the arriving flight and the departing connecting flight are operated by different carriers, the carrier that operated the arriving flight (i.e., the one that operates the first of the two flights that are connecting) is responsible for providing or ensuring the provision of this assistance, even if the passenger holds a separate ticket for the departing flight. It is permissible for the two carriers to mutually agree that the carrier operating the departing connecting flight (i.e., the second flight of the two) will provide this assistance, but the carrier operating the arriving flight remains responsible under this section for ensuring that the assistance is provided.
