In accordance with airline luggage regulations, dangerous objects are generally banned from carry-on and checked-in luggage on flights or are subject to restrictions.
However, these regulations vary depending on the airport, airline and country. You should therefore consult the website of your corresponding airport for detailed information on current regulations before you start your journey.
Some countries have more stringent regulations about carrying objects that can be used as weapons, both in and outside airports (for example, a pocket knife with a lockable blade). Please bear this in mind and make the necessary inquiries. In general, we advise you to stow pocket knives in checked-in luggage.
