The Transportation Security Administration is geared up for a busy week ahead, anticipating Thanksgiving holiday travel volumes to even surpass pre-pandemic levels. The day before Thanksgiving, the agency expects to check 2.5 million people.

The agency is preparing travelers with useful advice on everything from how to get through security smoothly to what foods they can (and cannot) bring with them in a carry-on suitcase. On busy days like Wednesday, Nov. 23, and Sunday, Nov. 27, the agency expects to screen as many as 2.5 million passengers.

Next week’s anticipated rise in travel demand will be handled by our organization. The TSA reminds holiday travelers flying on Turkey Day that certain foods cannot be brought on board in carry-on luggage to ensure that their journey is as smooth as gravy.

Travelers who want to bring liquids like gravy, cranberry sauce, wine, or jam must pack them in their checked luggage even though it is always acceptable to bring solid foods like cake, pie, or cooked meat like turkey on airplanes.

According to the organization, a liquid must be packed in a checked bag if it can be spilled, sprayed, spread pumped, or poured

Check the TSA’s “What Can I Bring?” website, which features a searchable list of both allowed and prohibited items, if a traveler is unsure of what items they can bring on board with them.

Additionally, travelers can submit inquiries to “@AskTSA” on Twitter or Facebook Messenger to inquire about any specific worries. Each day, including holidays and weekends, the staff is on hand from 8 a.m. to 6 p.m. ET.

The agency advises travelers to pack carefully when it comes to other prohibited items like firearms, which can only travel in checked baggage if they are unloaded, “properly packaged, and declared at the airline ticket counter.

Passports and driver’s licenses are examples of acceptable forms of identification that travelers should have with them. A REAL ID, an improved state-issued driver’s license or identity card, will be required starting in 2019 for passengers who intend to fly using a driver’s license.
