This rulemaking would examine requiring U.S. and foreign air carriers to adopt and adhere to customer service plans identifying essential services (meals, rebooking, hotel, transportation to or from hotel, timely customer service) and compensation which airlines would be required to provide to mitigate passenger inconveniences when the cause of a cancellation or delay for flights to, within and from the United States was due to circumstances within the airline's control. In addition, the rulemaking would define when a delay or cancellation would be considered controllable by the airline meaning passengers would be entitled to receive the essential services (including compensation) to mitigate their inconvenience. The rulemaking would also examine how best to ensure passenger awareness of the services and compensation that would be available to them following a controllable delay or cancellation.
