TSA-Approved Packing Essentials (Full Checklist)
Know exactly what you can bring through security — complete guide to TSA rules with approved alternatives.
Quick Answer
Start by reviewing TSA.gov's official lists before packing. Most essentials cost nothing extra—you likely own them already. The single most important rule: liquids, gels, and aerosols must be 3.4 ounces or smaller and packed in a clear quart-sized bag.
Introduction
Navigating TSA security rules saves time, prevents confiscation, and reduces airport stress. This guide provides a definitive checklist of what you can bring through security and approved alternatives for restricted items, so you pack with confidence and clarity.
Key Concepts
The 3-1-1 Liquids Rule
Liquids, gels, creams, and aerosols in containers of 3.4 fluid ounces or less go in one clear quart-sized plastic bag, one bag per passenger. This applies to toothpaste, shampoo, sunscreen, deodorant, and similar items. Solid items like bars of soap are exempt.

Carry-On vs. Checked Baggage
Different rules apply to items you bring on the plane versus luggage checked at baggage claim. Most restricted liquids and gels are prohibited in carry-on but allowed checked. Batteries, lighters, and some tools follow opposite rules depending on type and quantity.

Prohibited and Restricted Items
Prohibited items cannot travel at all—explosives, weapons, and certain tools are examples. Restricted items can travel but only under specific conditions, like lithium batteries in checked or carry-on bags with limits, or razors only in checked luggage, not carry-on.
TSA PreCheck Expedited Screening
TSA PreCheck is a paid program allowing eligible travelers to go through faster security screening with fewer restrictions, keeping shoes, belts, and light jackets on. Membership costs approximately $80 to $85 for five years and requires background checks and an in-person appointment.

Known Traveler Number Verification
Your Known Traveler Number appears on your boarding pass when flying and activates TSA PreCheck benefits at security. It links your identity to your trusted traveler status, enabling expedited processing when you provide it during flight booking.

Common Mistakes
Packing full-size toiletries in carry-on luggage
Transfer liquids like shampoo, lotion, and toothpaste to travel-size containers of 3.4 ounces or smaller, or purchase TSA-approved travel sets before flying. Check baggage allows full-size items without restriction.
Forgetting the quart-sized clear plastic bag
Place all 3-1-1 compliant liquids in a single, transparent quart-sized plastic bag. TSA requires this specific container; gallon bags or opaque bags will delay or deny entry through security.
Including lighters, matches, or flammables in luggage
Lighters are prohibited in both carry-on and checked bags. Matches are only allowed in checked baggage and must be safety-strike type. Leave these items at home or purchase them at your destination.
Packing sharp objects like razors or scissors improperly
Safety razors and disposable razors belong only in checked baggage with blade guards attached. Straight razors and box cutters are prohibited. Pack scissors with blades under four inches checked, not carry-on.
Not checking battery restrictions for electronics
Lithium batteries have strict limits. Spare lithium batteries are prohibited in checked bags but allowed in carry-on if under 100 watt-hours. Larger batteries or damaged batteries may be refused entirely.
Pro Tips
- ★Download the TSA's official mobile app to scan and verify any item before packing. The real-time database reflects recent rule changes and shows carry-on and checked baggage allowances instantly.
- ★Buy travel-size toiletries at your destination if you checked luggage didn't arrive. TSA allows carry-on sizes, so purchasing duplicates avoids repacking stress and ensures compliance.
- ★Label your 3-1-1 liquids bag clearly and place it on top of carry-on baggage. This speeds security screening because agents can remove it quickly for inspection without unpacking everything.
- ★Register for TSA PreCheck or Global Entry if you fly more than twice yearly. Expedited screening saves 20 to 30 minutes at security and allows some items to stay in bags during screening.
- ★Photograph your packed carry-on and checked bags before arriving at the airport. Documentation helps file claims for confiscated items and provides proof if luggage is damaged or opened by security.
