Which of the following is NOT required under the ACAA for passengers with disabilities?

The requirement related to companion seating arrangements under the Air Carrier Access Act (ACAA) is not explicitly mandated. While airlines are encouraged to assist passengers with disabilities in making travel arrangements, including seating next to companions if possible, there is no formal obligation requiring airlines to provide specific companion seating arrangements for passengers with disabilities.

In contrast, the other options are indeed requirements of the ACAA. Airlines must provide assistance during boarding and deplaning to ensure that individuals with disabilities can access the aircraft safely. Accessible flight information is also mandated, enabling passengers with disabilities to receive vital updates regarding their flight. Additionally, the safe transport of mobility aids is a critical requirement, ensuring that individual mobility devices are handled properly, minimizing the risk of damage, and allowing passengers to maintain their independence when traveling.
