The Federal Aviation Administration said May 25 will be the busiest single day over the May 24-30 period with about 51,200 flights that is the traditional kickoff to the busy U.S. summer travel season. There were about 321,000 flights in the same period in 2019. United Airlines said Tuesday it is planning for its busiest Memorial Day holiday in more than a decade, forecasting nearly 2.9 million passengers between May 25 and May 30.
