The bill wants to make sure airplanes have a good plan to keep flying smoothly, even when there's bad weather or other problems, so people don't get stuck at the airport. It also wants to check to make sure these plans are working well after a few years.

The Ensuring Airline Resiliency to Reduce Delays and Cancellations Act is a plan that tells airlines to figure out how to deal with bad weather and other problems that can mess up flights, and to keep checking and updating their plan. Later, a special group checks if the plans are working and tells the people in charge what they find.
