1. Passport + ESTA/Visa

2. REAL ID vs Passport (US Airport Security Screening 2025 Update)

TSA will fully enforce REAL ID starting May 7, 2025. However, if you’re an international traveler, your passport alone is fully valid for all US domestic and international flights.

• US residents → REAL ID or passport required
• International travelers → passport is enough
• Name mismatch → may trigger extra screening or denied boarding

3. 3-1-1 Liquid Rule — Still Active for US Airport Security Screening 2025

Despite rumors, the TSA 100ml/3.4oz liquid rule remains fully enforced in 2025.

• Up to 100ml per container
• All must fit in one 1-quart clear zip bag
• One bag per person
• Medication & baby items → allowed but must be declared

CT-equipped lanes may allow liquids to remain inside your bag—but the volume rule itself has not changed.

4. Electronics & Power Banks (US Airport Security Screening 2025)

Electronics are more about safety and convenience than regulation.

• Laptops & tablets → carry-on only
• Cameras & drone batteries → carry-on only
• Power banks → strictly prohibited in checked bags
• May be removed or rejected if placed in checked baggage

Some CT lanes don’t require taking laptops out, but screening varies by airport, so it’s best to be prepared either way.

5. Why US Airport Security Screening Feels Different Each Time

Travelers often feel US airport security is inconsistent. The truth? The rules are the same—equipment is not.

(1) Different Equipment at Different Airports

• CT scanners → no need to remove liquids or laptops
• Traditional X-ray → laptops and liquids must come out
• CAT scanners → ID-only screening

(2) Airport Size & Budget Differences

• Large hubs adopt new tech faster
• Smaller airports keep older systems longer

(3) Even the Same Airport Has Different Lane Types

• TSA PreCheck lanes
• Standard lanes
• K9 lanes
• Simplified or temporary lanes

LAX may require removing your laptop, while SFO may not—simply due to different equipment.
