TSA & Delta Air Lines Liquids Rule
49 CFR § 1540.111 — Aviation Security Authority
Title 49 of the Code of Federal Regulations (§ 1540.111) dictates the 3-1-1 liquids rule for passenger cabin baggage. Containers carrying hair straightener must be 3.4 fluid ounces (100 milliliters) or smaller by capacity. Larger containers that are only partially full are still prohibited in cabin baggage unless they fall under medical or infant care exemptions. Containers larger than 3.4 oz must be packed in checked luggage.
Security Checkpoint Screening Procedure
When passing through the TSA checkpoint with hair straightener, place your travel-sized container (3.4 oz / 100 mL or less) inside a clear, quart-sized plastic bag. If standard 2D X-ray machines are operating at your lane, extract the quart bag and lay it flat in a screening bin. At airports equipped with modern 3D CT computed tomography scanners, you may leave your liquids inside your bag unless instructed otherwise by Transportation Security Officers. Medical liquids or baby nourishment exceeding 3.4 oz must be declared immediately prior to screening for manual inspection or explosive trace detection (ETD) testing.
Step-by-Step Packing Guide for Delta Air Lines Passengers
Ensure hair straightener is completely turned off, unplugged, and cooled to room temperature before packing inside luggage.
Wrap the electrical cord loosely around the unit or secure it with a velcro tie; avoid tightly wrapping cords to protect internal wiring.
Check the voltage rating on hair straightener (110V vs 220V–240V); traveling overseas with single-voltage high-wattage styling tools requires a heavy-duty voltage converter, not just a plug adapter.
Cushion heating elements and motors by surrounding hair straightener with soft clothing inside your carry-on or checked luggage.
Any cordless styling device powered by butane cartridges or lithium-ion batteries must remain in carry-on baggage with its safety cap locked.
