How to Pack Cooking Spray (aerosol) for a Flight
Step-by-Step Traveler Decision Checklist
- 1 Placement Decision: Cabin: NO | Checked Hold: NO
- 2 Packing & Protection: The PAM can stays home: cooking sprays use flammable propellants that put them in hazmat territory, not the toiletry-aerosol exemption. A refillable pump or mister bottle with oil inside is the packable equivalent — it counts as an ordinary liquid.
- 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.
