Summary

Airlines and commercial airports must send emergency plans to the Secretary of Transportation within 90 days of this law. This includes any airline that flies scheduled or public charter passenger flights on planes with 30 or more seats, every commercial airport (large, medium, small, or nonhub), and any airport used for diversions. Airlines must file a plan for each airport they serve and for any airport where they control flight inventory. The airline plans must say how they will give food, drinking water, working restrooms, comfortable cabin temperatures, and medical help during delays; how they will share facilities and make gates available in an emergency; and how they will let passengers leave the plane after a long tarmac delay. A long tarmac delay means more than 3 hours for domestic flights and more than 4 hours for international flights. After such a delay, passengers must be offered the option to get off the plane and return to the terminal, and the airline must start moving the aircraft to a suitable place to disembark within 3 hours (domestic) or 4 hours (international) after the main door closed. This applies even if the flight was diverted, unless air traffic control or the pilot says it would harm airport operations or safety/security. Airport plans must cover deplaning, gate sharing, and a sterile area for people who haven’t cleared U.S. Customs. Airlines must update plans every 3 years and airports every 5 years. The Secretary has 60 days to approve or request changes to a plan, and if no action is taken it is treated as approved. Approved plans must be followed and made public online or in another way. Airlines must report any excessive tarmac delay to the Department of Transportation’s Aviation Consumer Protection Division within 30 days. The Secretary can set minimum plan standards as needed.
