TSA-approved list of carry‑on items in the U.S. flights

In a recent update, the Transportation Security Administration (TSA) has updated its list of items allowed in carry-on bags on U.S. domestic flights. The new policy is driven by the increasing use of advanced screening technologies, specifically Computed Tomography (CT) scanners, at all major airports across the U.S.


The new CT scanners generate 3D images of luggage contents. It enables security agents to detect potential threats in a much better way. They don’t need to do manual inspection of bags anymore. The TSA has relaxed its restrictions on many items that were previously limited or not at all allowed in carry-on luggage.

TSA-Allowed items in Carry-On bags

Under the latest updated, the travellers in the U.S. can now carry the following items through security checkpoints at airports equipped with CT technology:

Prescription and over-the-counter medications; liquid, gel, or aerosol forms are also permitted

Breast milk, infant formula, and baby food (in reasonable quantities)

Liquid-filled baby teethers

Fresh eggs, properly packed

Live fish, transported in water-filled containers

Biological specimens for medical or research purposes

Ice packs or gel packs, especially when used to keep medical items cool

Wet-cell batteries, under specific safety guidelines

Duty-free liquids, if sealed in tamper-evident bags provided at the point of purchase

Earlier these were restricted by the TSA’s well-known 3-1-1 liquids rule. As per the rule, the TSA limits liquids to 3.4 ounces (100 mL) per container, packed in a single quart-sized zip-top bag—but only at airports where CT scanners are in use. If you are departing from an airport without this upgraded technology, the standard liquid limits still apply.

For those who fly frequently with medical necessities, baby supplies, or fragile food items, it is an important change. Now parents will no longer have to split up baby formula or food into tiny containers. Similarly, individuals who need liquid medications or carry sensitive biological samples can now do so more easily.

This also marks a broader shift toward modernizing airport security. The CT scanners provide better threat detection, which allows for more flexible screening processes without compromising safety.

What travellers should keep in mind


Know your airport: Before flying, check if your departure airport has CT scanners installed. The relaxed rules only apply at these locations.

Pack smart: Though these items are now allowed, TSA officers still have the final say. Items may need to be removed from your bag for additional screening.

Follow duty-free rules: If you're carrying duty-free liquids, they must remain sealed in the official tamper-evident bags.

With these new improvements, the TSA’s aim is to phase out old security processes.
