Generally, it is not considered safe to put high-value items in checked luggage, and most travel experts—as well as airlines themselves—strongly advise against it. Checked bags are handled by numerous personnel and pass through "blind spots" in airport infrastructure where theft can occur, despite modern surveillance. Furthermore, most airline "Conditions of Carriage" explicitly state that they are not liable for the loss of jewelry, electronics, cash, or important documents stored in the cargo hold. In 2026, even with advanced tracking like AirTags, a tag only tells you where your bag is, not what is inside it. If a bag is lost or delayed, you could be without vital medications or expensive equipment for days. The best practice is to keep all "indispensable" valuables in your carry-on bag or on your person. If you must check a valuable item that is too large for the cabin, ensure you have comprehensive travel insurance and consider declaring a "higher value" at the check-in counter, which may involve a fee but increases the airline's legal liability limit for that specific bag.
