Sandwiches. Unless utterly soggy, sandwiches are a bit of a gray area with TSA. You can’t bring jars of jam or peanut butter on the plane, but a heavily spread PB&J (we’re talking about half an inch thick) doesn’t get any second glances.

Your food will need to fit inside your carry-on bag. Can I take food through airport security? Travellers are allowed to bring food through airport security. However, you should remove any food and snacks from your carry-on bag, along with your bagged liquids, to be screened separately.

Here’s a big list of food you can bring through airport security:

• Cakes (subject to additional inspection)
• Pies (subject to additional inspection)
• Sandwiches (wrapped)
• Bananas.
• Apples.
• Oranges.
• Sliced fruit (wrapped or in a container)
• Firm Cheese (wrapped)

To keep things fresh, bring a cooler (the traditional kind or one that plugs into the car). Meals: Whole-grain pasta salad or quinoa salad. Turkey and cheese sandwich on whole-wheat bread….

1. Sliced fresh fruit like melon and berries.
2. Snack bar.
3. Greek yogurt.
4. Cheese and whole-grain crackers.

Any solid foods like fruits, dry fruits, salads can be carried easily but food with a high liquid content (for instance, food with curries or sauces) is only allowed in containers of 100 ml regardless of the quantity inside.

Prohibited items in Cabin Baggage: Knives, scissors, Swiss army knives and other sharp instruments. Toy replicas of fire arms and ammunition. Weapons such as whips, nan-chakus, baton, or stun gun. Electronic devices which cannot be switched off.

According to the TSA website, any object that could potentially be used as a weapon is not permitted in the cabin. You must transport those items in your hold luggage instead. This includes, for example, firearms, rifles, ammunition, but also sporting equipment that could be weaponized.
