This rulemaking is intended to restore common sense governance while maintaining core accessibility protections for air travelers with disabilities. This rulemaking would address: (1) airlines’ liability when passengers’ wheelchairs or other assistive devices are not timely returned in the condition they were received; (2) frequency of required refresher training of airline employees and contractors; (3) notifications to passengers that check wheelchairs or scooters; and (4) reimbursements of the difference between the fare on a flight a wheelchair or scooter user took, and the fare on a flight that the wheelchair or scooter user would have taken if his or her wheelchair or scooter had been able to fit on the flight.
