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

(2) You may designate an adequate number of the seats used to provide seating accommodations required by §382.81 as “priority seats” for passengers with a disability.

(i) You must provide notice that all passengers assigned these seats (other than passengers with a disability listed in §382.81 of this part) are subject to being reassigned to another seat if necessary to provide a seating accommodation required by this section.

(ii) You may provide this notice through your computer reservation system, verbal information provided by reservation personnel, ticket notices, gate announcements, counter signs, seat cards or notices, frequent-flier literature, or other appropriate means.

(iii) You must assign a seat meeting the requirements of this section to a passenger with a disability listed in §382.81 of this part who requests the accommodation at the time the passenger makes the request. You may require such a passenger to check in and request the seating accommodation at least one hour before the standard check-in time for the flight. If all designated priority seats that would accommodate the passenger have been assigned to other passengers, you must reassign the seats of the other passengers as needed to provide the requested accommodation.

(iv) If a passenger with a disability listed in §382.81 does not check in at least an hour before the standard check-in time for the general public, you must meet the individual's request to the extent practicable, but you are not required to reassign a seat assigned to another passenger in order to do so.
