The Transportation Security Administration’s (TSA) wait times have become unpredictable, with staffing issues and unpaid workers exacerbating the problem. With federal workers screening passengers and bags without pay, experts predict that lines will vary by airport, but some check points may see significant delays. Travelers are advised to check security line wait times at their specific airport for the most up-to-date information, as programs like TSA PreCheck and Clear+ can help shorten wait times during a shutdown.
