Yes, you can take fast food through airport security. However, there are some restrictions. Solid food items can be transported in either your carry-on or checked baggage, while liquid or gel food items larger than 3.4 oz are not permitted in carry-on baggage and should be placed in checked baggage if possible[2].
Liquids, pastes, or gels, including food items like yogurt, soup, jams, and jellies, must be under 3.4 oz[2].
If a food item triggers an alarm during the screening process, it may be subject to additional screening or not allowed through the checkpoint[2].
