Which items are typically prohibited to carry in carry-on luggage on most flights for security reasons?

• A. Weapons, explosive devices, certain flammable items, and other dangerous goods
• B. Books and magazines
• C. Personal electronics
• D. Extra snacks

Answer: (A)

Dangerous goods restrictions are all about safety: items that could be used to harm passengers or crew or could ignite or explode on board are prohibited in carry-on luggage. Weapons, explosive devices, certain flammable items, and other dangerous goods fall into that category because they pose an immediate risk in the confined environment of an aircraft. That’s why this category is the one you’ll see barred from cabin baggage across most airlines and security regimes.

In contrast, everyday items like books, magazines, personal electronics, and extra snacks are typically allowed in carry-on after screening, since they don’t present the same immediate threat and can be managed by security and aircraft crew. Some items may have special restrictions or must be placed in checked luggage, but the principle remains: dangerous items risky to the cabin are not permitted in carry-on.
