The shutdown is over. Flights have resumed. Thanksgiving travelers might wonder: What now?

After lifting its shutdown-era flight restrictions on commercial airlines last week, the Federal Aviation Administration now says it's preparing for its busiest Thanksgiving week in 15 years, with more than 360,000 flights scheduled to take off in the U.S. between Monday and next Tuesday. That’s more than 17.8 million people who will be screened by the Transportation Security Administration.
