Flying with Cash

How Much You Can Carry & Declare

✈️ Is It Legal to Fly with Cash?

Yes, it’s legal to fly with cash both domestically and internationally. However, there are important regulations, declaration thresholds, and safety practices every traveler should understand. Flying with large sums of money can attract scrutiny from airport security or customs agents, so it’s crucial to know the rules to avoid delays, confiscation, or legal issues.

🧳 How Much Cash Can You Fly With Domestically in the U.S.?

There is no official limit to how much cash you can carry on a domestic U.S. flight. TSA does not restrict cash, but they may flag travelers carrying unusually large sums for additional screening. Be prepared to explain the source and purpose of the funds if questioned. Always keep cash on your person: never check it in.

🌎 What Happens If You Travel Internationally with More Than $10,000?

When entering or leaving the U.S. with over $10,000 in cash or monetary instruments, you must declare it by submitting FinCEN Form 105 to U.S. Customs and Border Protection. This rule applies to each individual, not families or groups combined. Failure to declare cash above this threshold can result in seizure of the entire amount and additional penalties.

💵 What Counts as 'Cash' for Airline & Customs Declarations?

Cash isn’t just paper money. For customs and declaration purposes, it also includes:

Coins and banknotes
Traveler’s checks
Money orders
Negotiable instruments (e.g., checks, bonds) If you're traveling with these items and their total value exceeds $10,000, you must report them when crossing international borders.

🔐 How to Travel Safely with Cash

Follow these tips to protect your cash and reduce risks:

Keep cash in your carry-on or on your person: never in checked luggage
Use a money belt or concealed pouch
Avoid showing or counting cash in public
Split large sums between different safe places
Be prepared to explain the purpose of the funds if asked by authorities

🚨 Will TSA or Airport Security Seize My Cash?

TSA does not have authority to seize cash solely because of the amount. Their job is to screen for security threats, not investigate finances. However, if TSA suspects criminal activity, they may notify law enforcement, who can question you and potentially seize funds under civil asset forfeiture laws.

For example, in 2019, a traveler flying from Dallas to Chicago was stopped with $43,000 in cash. Although no criminal charges were filed, the money was seized under suspicion. The case later made headlines, prompting calls for reform of cash seizure practices. While rare, these scenarios highlight the importance of carrying proof of the source of your money: such as bank withdrawal slips, invoices, or business records.

If you're traveling with a significant amount of cash, always remain calm, cooperative, and prepared to answer basic questions about its origin and purpose.

🌐 What Are the Rules for Carrying Cash in Other Countries?

Many countries enforce their own declaration limits for travelers entering or exiting with cash. Common thresholds:

EU countries: €10,000
Australia: AUD 10,000
Canada: CAD 10,000
UK: £10,000 Always check your destination country’s customs website or speak with your airline to confirm requirements before travel.
