TSA & United Airlines 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 cooking oil 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 cooking oil, 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 United Airlines Passengers
Verify your container holds 3.4 oz (100 ml) or less. Larger bottles of cooking oil must travel in checked luggage unless purchased airside at a duty-free outlet.
Seal the cooking oil cap tightly to prevent leaks caused by cabin pressure changes, then place it inside a clear, resealable 1-quart plastic bag.
Pack the sealed bag in an outer pocket of your carry-on for fast, one-hand retrieval at the TSA liquids checkpoint.
At the security lane, remove the clear liquids bag from your carry-on and lay it flat in a screening tray on its own.
If travelling internationally, check the destination country's import limits on volumetric liquids or spirits before boarding.
