TSA Carry-On Rules for 2025

Note: This blog post is based on the latest TSA guidelines as of 2025. For the most current information, always refer to the official TSA website.

Air travel—a delightful blend of excitement, anticipation, and the occasional frantic rummage through your carry-on at the security checkpoint. As we soar into 2025, the Transportation Security Administration (TSA) has introduced some updates to their carry-on regulations. Fear not, bruh! I’m here for it and I’ll ensure your journey is as smooth as your in-flight beverage (which, by the way, still adheres to the 3-1-1 liquids rule).

1. The 3-1-1 Liquids Rule: Some Things Never Change

Let's start with a classic—the 3-1-1 rule. If you can spill it, spray it, spread it, pump it, or pour it, it's considered a liquid and must be packed accordingly. Each passenger is allowed:

• 3.4 ounces (100 milliliters) per container.

• 1 quart-sized, clear, resealable bag for all liquid containers.

• 1 bag per passenger.

This means your artisanal beard oil, lavender-scented hand sanitizer, and that trendy matcha-infused facial mist all need to fit within these parameters. Speaking of hand sanitizer...

2. Hand Sanitizer Allowance: Back to Basics

Remember the good old days when we could carry up to 12 ounces of hand sanitizer? Well, those days have flown by. As of 2025, the TSA has reverted to the standard 3.4-ounce limit for hand sanitizers. So, unless you're planning to open a mid-flight pop-up shop, keep those sanitizers travel-sized and snug in your quart-sized bag.

3. Firearms in Carry-On Bags: A Hefty No-No

While it might seem obvious to some, it's worth reiterating—firearms are strictly prohibited in carry-on luggage. Attempting to bring a firearm through the security checkpoint can result in:

• Immediate involvement of law enforcement (cue the flashing lights and dramatic music).

• Civil penalties of up to $15,000 for the first offense.

• Revocation of TSA PreCheck eligibility for a minimum of five years. A second violation? Say goodbye to PreCheck forever.

So, unless your dream vacation involves a complimentary stay in a local jail, it's best to leave the firearms at home or follow proper procedures for transporting them in checked baggage.

4. REAL ID Enforcement: Your Ticket to Ride

Starting May 7, 2025, the TSA will enforce the REAL ID requirements. This means:

• Your state-issued driver's license or identification card must be REAL ID-compliant to board domestic flights.

• Not sure if your ID makes the cut? Look for a star marking on your license or check with your state's department of motor vehicles.

Avoid the dreaded "walk of shame" back to the check-in counter by ensuring your ID is up to snuff before arriving at the airport.

(When we were your age, we could get on a plane with just a Costco membership card.)

5. Airline-Specific Carry-On Dimensions: Size Matters

While the TSA sets the security standards, individual airlines dictate the size and weight limits for carry-on luggage. Recent updates include:

• American Airlines is planning to adjust its carry-on policies to align with stricter international standards. While specifics are yet to be finalized, it's anticipated that allowable dimensions may decrease.

To avoid the embarrassment of trying to stuff an oversized bag into the sizer (and subsequently into the overhead bin), always check your airline's current carry-on dimensions before packing.

6. Packing Smart: Start with an Empty Bag

A wise traveler once said, "The journey of a thousand miles begins with an empty suitcase." Or something like that. Starting with an empty bag helps ensure you don't inadvertently bring prohibited items. Need guidance on what's allowed? The TSA's “What Can I Bring?” page is your trusty co-pilot.

7. Arrive Early: Time Is on Your Side

With passenger volumes reaching new heights, it's prudent to:

• Arrive at least two hours before domestic flights.

• Arrive three hours before international flights.

This buffer allows ample time for parking, check-in, security screening, and perhaps even a leisurely stroll to your gate (or a quick detour to grab that overpriced airport latte).

8. Medication and Special Items: Declare and Separate

Traveling with medications or special items? Here's the lowdown:

• Medications in liquid form are allowed in quantities exceeding 3.4 ounces but must be declared at the checkpoint.

• Items like baby formula, breast milk, and toddler drinks are also exempt from the 3-1-1 rule but should be separated and declared during screening.

Transparency is key—both in your quart-sized bag and in your communications with TSA officers.

9. Prohibited Items: Leave the Nunchucks at Home

While some items are obvious no-gos (looking at you, nunchucks), others might surprise you. For instance:

• Magic 8 Balls are considered liquids and must adhere to the 3-1-1 rule. So, unless you want to hear, "Outlook not so good" at the checkpoint, it's best to pack them in checked luggage.

When in doubt, consult the TSA's prohibited items list to ensure your cherished belongings don't end up in the confiscation bin.

10. TSA PreCheck and CLEAR: Fast-Track Your Experience

For frequent flyers or those who simply despise long lines (which, let's be honest, is all of us), programs like TSA PreCheck and CLEAR offer expedited screening processes. Benefits include:

• Keeping shoes, belts, and light jackets on.

• Leaving laptops and compliant liquids in your bag.

Enrollment involves a background check and fee but can be a game-changer for the avid traveler.
