Ten Things Not Allowed in Flight – Take the Flight for Wonderful Experiences

While packing for your next vacation, you should also take the time to understand restrictions enforced by airlines to ensure passenger safety. Here are ten things not allowed on a flight. 


Explosives and Flammable Materials

You cannot, under any circumstances, carry explosive substances and flammable materials on board a flight. This category of items includes fireworks, flares, dynamite and anything else that could be hazardous. So, if you have anything that could pose a danger to your own safety and the safety of other passengers, make sure to leave them at home.


 Weapons and Firearms

Firearms, guns, ammunition, and all other types of weapons are explicitly prohibited from being carried in either carry-on or checked baggage. Knives, swords, tasers and pepper spray are a few examples of weapons and firearms. Therefore, when you browse and book flights, make sure to get in touch with the airline and get more information on what can and cannot be brought on a flight. Most airlines, like InterCaribbean Airways, have dedicated information centres that you can easily get in touch with. 


Liquids over 100 ml

Passengers are not allowed to carry bottles with liquids that exceed the permitted amount of 100 ml. Beverages, gels, creams, aerosols, lotions, and aerosols belong in the category of liquids that are not allowed on an aircraft. That being said, you can, however, carry small containers of liquid as long as they are placed in a clear, resealable plastic bag and adhere to the 3-1-1 rule.


 Sharp Objects

If there’s anything that’s sharp enough and can be used as a weapon, you should leave that item at home. This category of items includes knives, except plastic or rounded butter knives, razor blades, box cutters, and scissors. Anything with a sharp and pointy end that can be used to cause harm will not be allowed on a flight. 



You cannot carry batteries that are considered hazardous in your carry-on or luggage. However, you can carry electronic devices like smartphones and laptops as the batteries contained within them are not considered dangerous. 


Corrosive Substances

Corrosive substances that can cause damage to the airport and endanger the safety of passengers are not allowed on flights. These substances include wet cell batteries, acids, and mercury. If you have any item of this nature in your luggage, make sure to let the airline know. 


 Infectious Materials

Anything that could be infectious is not allowed on an aircraft. These things include biological substances that could spread diseases. Live animals, except service animals, and human or animal remains are examples of infectious materials. 


Radioactive Materials

You are not allowed to bring materials like industrial sources and medical equipment on the aircraft. This doesn’t mean that these materials cannot be transported; this only means that you need to follow the strict guidelines laid out by the airline. If you have anything that falls into the category of radioactive materials, you need to get in touch with the airline for more information and find out whether you can carry them in your luggage.  


 Illegal Drugs and Narcotics

Carrying illegal drugs and narcotics not only violate the regulations of airlines but also breaks national and international laws. Keep in mind that airport security is trained and highly vigilant in detecting and preventing the transportation of illegal substances. Remember that if you get caught carrying these items, you will face severe consequences. 


A Final Word

Understanding airline regulations and restrictions is vital if you want to safe and enjoyable journey. It not only protects you from harm but also protects your fellow passengers. You should always be sure to check with the airline to make sure you don’t have anything in your luggage that’s not allowed. Carrying these prohibited items can take the fun out of your vacation and cause lengthy delays.
