3-1-1 RULE AND LIQUIDS
Unless you have avoided flying since 2001, you are likely aware of the 3-1-1 rule that states you have to pack liquids (like shampoo) in a clear, plastic zip lock to go through security. The liquids have to be 3.4 ounces or less as well. Unfortunately, TSA applies these rules to food that they consider to be liquid.
The following items are listed as a liquid/gel on TSA's website: - Nut butter (squeeze packs included) - Jam/jelly - Yogurt - Oil and vinegar - Creamy cheese - Salsa - Soups Items that are not specifically identified as liquid or gel on the TSA website, but fit the same description include: - Pudding/ Jell-O - Hummus - Salad dressing - Fruit cups with syrup - Apple sauce
GEL PACKS & TIPS TO KEEP YOUR FOOD COLD
The good news is TSA will allow you to go through security with an icepack, as long as the icepack is frozen solid during screening. The TSA website states, "If frozen liquid items are partially melted, slushy, or have any liquid at the bottom of the container, they must meet 3-1-1 liquids requirements." - Make sure you freeze your gel packs for at least 24 hours before your trip. - Pack your gel packs right before you head to the airport. - Leave your 6 Pack Bag in the trunk of your car (out of the sun) while you drive to the airport. - Keep everything in your bag colder by completely freezing at least one of your meals. Place the frozen meal container in the middle of the non-frozen. I place the frozen meal in the middle row of my Innovator along with the frozen gel packs and have never had any issues. - If you are concerned about your ice packs melting before you get to security, add some other frozen items to your 6 Pack Bag like frozen grapes, peas or carrots. This will help to keep the entire bag cooler, keeping the gel packs colder longer. - Pack a few extra zip lock bags in case your gel packs do get slushy and you have to throw them away. You can fill the zip lock bags with ice after you have been through security to keep your food cold.
