How to Pack Cash for a Flight
Step-by-Step Traveler Decision Checklist
- 1 Placement Decision: Cabin: YES | Checked Hold: YES
- 2 Packing & Protection: The number everyone asks: $10,000 is a declaration threshold, not a limit — you can carry more if you declare it. Keep cash in carry-on, spread across two places, and expect polite questions at security for very large sums.
- 3 Checkpoint Protocol: Keep packed securely inside carry-on luggage.
- 4 Airline & Authority Boundary: Check airline baggage policies for individual carry-on size and weight limits.
