I'll search for the current TSA liquid restrictions for air travel to give you the most up-to-date information. Based on TSA regulations, here are the liquid restrictions for air travel:

Carry-On Baggage

You can bring liquids in your carry-on following the 3-1-1 rule:

• 3.4 ounces (100 milliliters) or less per container
• 1 quart-sized clear bag to hold all liquid containers
• 1 bag per passenger

This rule applies to all liquids, gels, aerosols, creams, and pastes. Each individual container must be 3.4 ounces or smaller, and all containers must fit in a single quart-sized bag.

Exceptions for Carry-On

• Duty-free liquids purchased after security screening in secure, tamper-evident bags
• Medications, baby formula, and breast milk (subject to additional screening)
• Essential liquids for medical purposes

Checked Baggage

There are no size restrictions for liquids in checked baggage. You can pack containers larger than 3.4 ounces in your checked luggage without limitation.

Current Updates

As of 2024, while the 3.4-ounce limit remains in effect, the TSA has relaxed enforcement of requiring liquids to be in a clear quart-sized bag at some airports, though liquids should still be able to fit in such a bag [1].

The TSA recommends packing any liquids over 3.4 ounces in checked baggage to avoid complications during security screening [2].
