How to Pack Cheese for a Flight
Step-by-Step Traveler Decision Checklist
- 1 Placement Decision: Cabin: RESTRICTED | Checked Hold: YES
- 2 Packing & Protection: TSA draws the dairy line at spreadability: a two-pound wheel of aged cheddar walks through untouched, while a 4 oz tub of cream cheese counts as a liquid. Fly the whole wheel home in your cabin bag and only the camembert needs the quart bag.
- 3 Checkpoint Protocol: Place in clear 1-quart bag and place in screening bin.
- 4 Airline & Authority Boundary: Check airline baggage policies for individual carry-on size and weight limits.
