Travelers must follow customs regulations when carrying gold or cash on domestic and international flights to avoid legal issues. Different countries set limits on how much gold and cash passengers can carry, so understanding these rules is crucial. On domestic flights, passengers can usually carry gold jewelry without restrictions. However, carrying gold bars or coins might require declaration or payment of duties. Some airlines also set limits on gold in checked baggage, requiring travelers to store valuables in carry-on luggage for security.

International travel has stricter rules. In India, passengers can bring up to 1 kilogram of gold after paying customs duty. Exceeding this limit may lead to seizure or require proof of ownership. In the United States, travelers can carry any amount of gold but must declare gold coins, medals, or bullion upon entry. Failure to declare can result in penalties. Some countries prohibit large gold imports without prior approval, while others impose high duties to control foreign exchange reserves.

Cash regulations also vary. Most countries allow travelers to carry any amount of cash on domestic flights. However, authorities may question large sums to prevent illegal activities. For international travel, many countries require passengers to declare amounts exceeding $10,000 or its equivalent in another currency. Undeclared cash above the threshold can lead to fines or confiscation.

To avoid problems, travelers should declare valuables when required and carry receipts or bank statements as proof. Security is also important. Carrying large amounts of cash or gold in checked luggage increases the risk of loss or theft. Keeping valuables in carry-on luggage and informing security personnel discreetly can ensure a smooth journey. Researching customs rules before travel helps prevent unexpected issues at the airport.
