RICHMOND, Va. (WRIC) -- The Transportation Security Administration (TSA) projects to screen millions of people during what it says will be the busiest Thanksgiving travel period on record. According to TSA, the agency projects to screen 18.3 million people from Tuesday, Nov. 26 to Monday, Dec. 2, representing a volume increase of about 6% from this time in 2023. The agency expects to screen more than 2.8 million people on Tuesday, Nov. 26, and more than 3 million on both Wednesday, Nov. 27 and Sunday, Dec. 1. The agency said it predicts these three days to be the busiest travel days for the Thanksgiving holiday. “This holiday season is expected to be one of the busiest travel periods on record, and the vigilant people of the Transportation Security Administration stand ready to ensure the security and ease of travel,” said Secretary of Homeland Security Alejandro N. Mayorkas. “Many members of the TSA workforce will be on duty throughout Thanksgiving Day and week and I am immensely grateful for their selfless dedication and professionalism." TSA said it has screened more than 2.9 million passengers on multiple days in 2024, but the record for the heaviest passenger volume in TSA history was on Sunday, July 7, when Transportation Security Officers reportedly screened more than 3 million people at airport security checkpoints nationwide.  The agency said it may exceed that record this Thanksgiving travel period. To travel with ease, TSA advises passengers to pack smart and start with an empty bag as those who do so are less likely to bring prohibited items through the checkpoint. According to TSA, all liquids, gels and aerosols must be 3.4 ounces or less when packed in a carry-on bag. Certain foods, such as gravy, cranberry sauce, wine, jam and preserves – which are considered liquids or gels – must be packed in a checked bag if they exceed 3.4 ounces. TSA said passengers may bring solid foods, such as cakes and other baked goods, through the checkpoint. To view information about prohibited items, visit TSA's website.
