§ 382.95
What are carriers' general obligations with respect to boarding and deplaning assistance?
(a) As a carrier, you must promptly provide or ensure the provision of assistance requested by or on behalf of passengers with a disability, or offered by carrier or airport operator personnel and accepted by passengers with a disability, in enplaning and deplaning. This assistance must include, as needed, the services of personnel and the use of ground wheelchairs, accessible motorized carts, boarding wheelchairs, and/or on-board wheelchairs where provided in accordance with this part, and ramps or mechanical lifts.
(b) As a carrier, you must, except as otherwise provided in this subpart, provide boarding and deplaning assistance through the use of lifts or ramps at any U.S. commercial service airport with 10,000 or more annual enplanements where boarding and deplaning by level-entry loading bridges or accessible passenger lounges is not available.
