Delta Air Lines Carriage & Security Policy
49 CFR § 1540.111 — IATA & Aviation Standards
Carriage of peanut butter is governed by TSA security directives under 49 CFR § 1540.111 regarding passenger screening and baggage security. Security rules distinguish sharply between accessible passenger cabin space (where items that could serve as weapons or hazards are prohibited) and cargo hold baggage (where items are safely stowed during flight).
Security Checkpoint Screening Procedure
At the airport screening lane, peanut butter will pass through standard X-ray or CT scanning equipment. Keep peanut butter neatly arranged in your luggage so officers can get a clear image. If an item appears opaque or clustered with wires or dense materials on the monitor, a secondary manual bag search will be conducted. Cooperate with TSA personnel and allow them to inspect the item without opening sealed packaging yourself.
Step-by-Step Packing Guide for Delta Air Lines Passengers
Confirm whether peanut butter is classified as a solid or a liquid/gel — spreads, pastes, and purees fall under the TSA 3-1-1 rule and must fit in your liquids bag.
Wrap individual pieces in food-grade plastic wrap, foil, or an airtight container to maintain freshness and prevent crushing in a packed bag.
Place fresh produce or loose food items in an easily accessible top compartment for rapid declaration at customs checkpoints.
Consume or properly dispose of fresh foods before crossing international borders — agricultural customs inspectors frequently confiscate fresh produce.
Ensure all food items are fully sealed to prevent odours or liquid drips inside the aircraft cabin.
