10 NEW Carry-On Rules (Don't Get Caught at TSA!)
As travel rules and security enforcement tighten up, knowing the exact regulations before arriving at the airport helps you breeze through security without surprises. Here are 10 essential carry-on and TSA rules to keep in mind:
📱 1. Ask TSA Before You Pack: Not sure if an item is allowed? Text AskTSA at 275-872 for quick verification before heading out.
👜 2. Know Your Personal Item Size Limits: Always measure your under-seat personal item and stick to the airline's exact dimension limits to avoid getting stopped at the gate.
📏 3. Standard Carry-On Dimensions: For major US carriers like American, Delta, and United, the limit is 22 x 14 x 9 inches (wheels and handles included).
🥜 4. The "Spread It, It’s a Liquid" Rule: TSA classifies peanut butter, jam, honey, and soft cheeses as liquids/gels—keep them under 3.4 oz or in your quart-sized bag.
💧 5. The Liquids Rule Remains Unchanged: The classic 3.4 oz (100ml) rule in a clear quart-size bag is still fully enforced (don't fall for full-water-bottle rumors).
👟 6. Follow Your Lane (New Scanners): With modern TSA scanners at many checkpoints, shoes can often stay on—just follow the agent's lane instructions.
💊 7. Gate-Checked Bag Sweep: If your bag gets gate-checked at the last minute, instantly pull out your medications, power banks, and valuables first.
🎒 8. Power Banks Stay Out of Overhead Bins: Never store spare lithium power banks in overhead bins; they must remain accessible in your under-seat personal item.
🔋 9. Two is the Limit: Most airlines cap you at a maximum of two spare power banks per passenger.
⚡ 10. The 100 Watt-Hour Charger Limit: Check the label on your power bank—FAA rules cap personal portable chargers at 100 Wh or less (roughly 26,000 mAh).
