Understanding Liquid Restrictions

One of the most common issues travelers face relates to "liquid restrictions". The Transportation Security Administration (TSA) outlines that any liquid, gel, or aerosol must not exceed 3.4 ounces (100 milliliters) per container. All containers must fit into a single one-quart bag. This rule applies to beverages, shampoos, lotions, and other consumables. If you are carrying larger quantities, these must be packed in checked luggage.

Medications and Baby Supplies

While many items are prohibited, there are exceptions for "medications" and baby supplies. Passengers are allowed to carry necessary medications in larger quantities than 3.4 ounces, provided they are declared at security. Similarly, baby formula, breast milk, and juice for infants are permitted, but they must also be declared at the checkpoint.

Tips for a Smooth Security Checkpoint Experience

To ensure a hassle-free experience at the security checkpoint, consider the following tips:

• Check the latest TSA guidelines before traveling.
• Pack prohibited items in your checked luggage.
• Keep your quart-sized bag of liquids easily accessible.
• Declare any larger liquid items, medications, or baby supplies at security.

Conclusion

Knowing what is "not allowed on a plane carry-on" is crucial for every traveler. By being informed about prohibited items, you can avoid unnecessary delays and enjoy a more pleasant journey. Always check with your airline and the TSA for the most current regulations, as these can change periodically. Safe travels!
