Know the TSA’s Liquid Rule

The Transportation Security Administration (TSA) allows passengers to bring a quart-sized bag of liquids, aerosols, gels, creams, and pastes in their carry-on bags. But each container must not exceed 3.4 ounces (100 milliliters). Here’s why:

“The TSA’s liquids rule is designed to help keep passengers safe and secure while flying,” said TSA Administrator David Pekoske. “It’s important for travelers to understand what they can and cannot bring in their carry-on bags to help speed up the screening process and ensure a hassle-free travel experience.”

My Personal Liquid Rule Experience

On a recent trip, I learned the hard way that a 5-ounce bottle of hair gel is a no-go. My advice? Stick to travel-sized toiletries and save yourself the headache.

Prohibited Items and Firearms Regulations

In 2019, the TSA screened over 800 million passengers and found over 4,400 firearms in carry-on bags, a 5% increase from the previous year. So, always double-check your luggage for prohibited items, including firearms, sharp objects, and flammable substances.

Insider Tip: Check the TSA Website for Updates

Before each trip, visit the TSA website for the latest updates on prohibited items and regulations. Trust me, you don’t want to be the one holding up the line.

Hassle-Free Packing and Security Checks

Now that you know the rules, here are some insider tips to make your next flight smooth sailing:

  • Layer up: Dress in layers for easy removal at security checkpoints.
  • Keep electronics accessible: Place laptops, tablets, and other large electronics in easy-to-reach spots in your carry-on.
  • Prepare your liquids: Have your quart-sized bag of liquids ready to go when you reach the security checkpoint.

Packing Like a Pro: Tips for Organizing Your Carry-On

You know the rules, but fitting everything into your carry-on can still be a challenge. Here are some expert tips for packing like a pro:

  • Roll, don’t fold: Rolling your clothes instead of folding them can save space and prevent wrinkles.
  • Use packing cubes: Packing cubes can help you stay organized and maximize space in your carry-on.
