Can I bring plastic grocery bags on a plane?

Yes, you can generally carry plastic bags on a plane, but there are some regulations and guidelines to consider. Plastic bags, such as Ziploc bags or clear resealable bags, are commonly used for carrying liquids, gels, and other items in your carry-on baggage.

For the TSA, which regulates travel in the United States, all liquids, gels, and aerosols must be in containers that are 3.4 ounces (100 milliliters) or less. All liquids must fit into a single, clear quart-size bag — passengers can only pack one of these bags in their carry-on.

The bag has to be able to close and be sealed – overstuffed plastic bags will not be accepted and you can't tie or knot the top of the bag. The maximum amount of liquid in total that you can carry onto a flight is one litre. You must take your bags out of your hand luggage and show at airport security.

Solid food items (not liquids or gels) can be transported in either your carry-on or checked bags. Liquid or gel food items larger than 3.4 oz are not allowed in carry-on bags and should be placed in your checked bags if possible.

Firearms, ammunition, and fireworks are prohibited, as are all knives and safety razors (including pocket knives and Swiss Army knives). Straight razors and replacement blades for straight razors are also not allowed. Most tools also cannot be packed in carry-on luggage, as they have the potential to cause harm.

Toothpaste is considered a liquid by the TSA (Transport Security Agency), even though it's technically a paste. In fact, all pastes, gels, waxes, and lotions are also classified as liquids. And even today, these substances are still restricted by the 3-1-1 rule in hand luggage due to safety threats.

If containers are larger than 3.4 ounces (100 ml), they won't be allowed through security, and the security officer will discard them. However, you can bring an empty reusable water bottle of any size through security and fill it up after you've gone through the checkpoint.
