Keep your luggage close to you at all times. Use a luggage lock to secure your bags. Avoid leaving your luggage unattended in public areas. Consider using a luggage tracking device or app. Avoid displaying expensive items or valuables in your luggage to deter theft. Be aware of your surroundings and report any suspicious activity to authorities. Choose a seat or cabin near the luggage storage area to keep an eye on it during the trip. Consider purchasing travel insurance that covers lost or stolen luggage in case of emergency. Keep your passport, tickets, and other important documents with you at all times. Do not leave them in your luggage.
