United Airlines Carriage & Security Policy

49 CFR § 1540.111 — IATA & Aviation Standards

Carriage of formula 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, formula will pass through standard X-ray or CT scanning equipment. Keep formula 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 United Airlines Passengers

Step 1

Baby food, formula, breast milk, and juice are exempt from the 3-1-1 liquids rule — you may carry reasonable quantities regardless of container size.

Step 2

Inform the TSA officer at the checkpoint that you are carrying baby items; they may test liquids separately but cannot require you to open sealed formula.

Step 3

Pack nappies, wipes, and a change of clothes near the top of your carry-on for quick in-flight access.

Step 4

Carry a small portable changing mat in your bag for use on the aircraft or in airport facilities.

Step 5

If travelling with sterilised equipment, keep items in sealed, sterile pouches until needed to maintain hygiene during transit.
