Air Carrier Access Act Technical Assistance Manual (2005)

If Aircraft is Substituted, Make an Effort to Accommodate

Even if a passenger with a disability provides advance notice, sometimes weather or mechanical problems require cancellation of the flight altogether or the substitution of another aircraft. Under these circumstances, you must, to the maximum extent feasible, assist in providing the accommodation originally requested by the passenger with a disability. [Sec. 382.33(f)]
