Travelers need to abide by TSA restrictions on carry-on liquids, gels, and spreadable items which are limited to 3.4 ounces. While Thanksgiving turkey is allowed, items like yogurt, hummus, and peanut butter are commonly confiscated. The status of cranberry sauce varies based on its liquidity. Remember, if it can be spread, pumped, or poured, it qualifies as a liquid under TSA rules. Check containers for compliance or opt for checked luggage.
