Are passengers allowed to carry their own alcohol in carry-on baggage?

Passengers are allowed to carry their own alcohol in carry-on baggage, but there are specific regulations that must be adhered to, particularly concerning liquid limits. According to airline policies and aviation security regulations, liquids in carry-on baggage must not exceed 100 ml per container, and all containers must fit within a single, transparent, resealable plastic bag with a maximum capacity of 1 liter. This is essential because these regulations are in place to ensure safety and mitigate risks associated with carrying liquids on board.

While passengers can bring small amounts of alcohol as long as they follow these rules, other choices provide misleading information. For instance, alcohol is not strictly prohibited; rather, it is permitted under certain conditions. Additionally, declaring alcohol at security is not a requirement unless it exceeds the allowable limits. Lastly, while passengers can purchase alcohol at the airport, they are not restricted to only that option, as personal alcohol within the permissible limits can also be carried.
