Prohibited & Allowed Items

The beginning of any air travel entails travelers packing their bags and heading out to wherever they might go. But there are certain restrictions on what you can carry aboard the plane, and what you cannot. But don't worry; even though the Transportation Security Administration holds maximum security when it comes to carry-on luggage, you can still bring things onboard, provided that you follow certain rules, such as: 

1. Liquids must be 3.4 ounces 100 mL maximum. Gels, lotions, shampoo, lips sticks, and toothpaste may all be brought into the plane, as long as they are less than this limit. All these pieces must be contained in a zipper-lined plastic bag with a maximum of 1 L. In the United States, passengers must adhere to the 3-1-1 rule for liquids ( : 3.4 ounces, or smaller, of any liquid or gel, 1 quart-sized clear plastic, and 1 bag per traveler, which must be placed in a security bin.

NOTE: Medications, breast milk, and baby formula, which exceed three ounces are allowed, but you must declare these items for inspection at the checkpoint. 

2. Most airlines, besides the standard cabin baggage allowance, allow passengers to carry items such as a briefcase, a laptop, a small backpack, or handbag. 

3. Canes, walkers, and crutches can also be brought, but the wheelchair solely depends if there is cabin stowage available.  Small bats, pool cues, hockey and lacorosse sticks, and 2 golf clubs are also allowed.

4. When traveling with a child or infant, you should have a car safety seat that is approved, a small bag for your food (just in case someone gets hungry), nappies, and a collapsible stroller that is umbrella-type, which, again, depends if there is cabin stowage available. 

5. Musical instruments must be inside a sturdy and protective case, with edges that are round. Soft cases will not be accepted, and hard cases would not be provided by the airline. Please note that musical instruments brought onboard are still part of your Cabin Baggage Allowance. It should preferably be 32 kgs, for the combined weight of the case and the instrument. 

6. The carry on luggage dimensions depend on the airline that you choose, since there is a lack in standardization. So please note that once you already chose your airline, you should find information concerning on your luggage dimensions.

7. Duty free items, such as books, mobile phones, laptops, and digital cameras, to name a few, can be brought but would be included in your cabin baggage allowance.

1. Most sharps object cannot be carried. This includes swords, sabers, ice picks, razor-type blades, meat cleavers, and box cutters. Of course, besides scissors all these cannot be brought onboard, but you need to wrap those blades securely and safely; who knows who it might fall into.
