According to the TSA, you are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams, and pastes in your carry-on bag and through the checkpoint. These are limited to travel-sized containers that are 3.4 ounces (100 milliliters) or less per item. The quart-sized bag should be placed in a separate bin during the screening process to facilitate the screening process. Any liquid, aerosol, gel, cream, or paste that alarms during screening will require additional screening. If you have duty-free liquids, you may carry them in a secure, tamper-evident bag in your carry-on bag if the liquids were purchased internationally and you are traveling to the United States with a connecting flight. The liquids must be packed in a transparent, secure, tamper-evident bag by the retailer and not show signs of tampering when presented to TSA for screening. The original receipt for the liquids must be present, and the purchase must have been made within 48 hours.
Exceptions to the 3.4-ounce limit are made for items you would need during your flight or at your destination, if the items are unavailable at your destination and cannot be purchased after the security checkpoint. This usually means any of the following items: baby and toddler drinks and food, including puree pouches, breast milk, and infant formula.
Liquid medications that are not prescriptions and contact lens solutions are limited to 3.4 ounces, but TSA does allow larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities for your trip, with the caveat that you must declare them to security officers first. Hand sanitizers of up to 12 ounces are allowed since TSA understands that COVID-19 is at the forefront of travelers minds.
In summary, you can bring a quart-sized bag of liquids, aerosols, gels, creams, and pastes in your carry-on bag and through the checkpoint, limited to travel-sized containers that are 3.4 ounces (100 milliliters) or less per item. Exceptions are made for items you would need during your flight or at your destination, if the items are unavailable at your destination and cannot be purchased after the security checkpoint.
