This article gives you clear steps to breeze through security, explains the latest TSA rules for 2025, and unpacks packing tips for budget-friendly travel. Start your Vegas adventure with less stress and more time for what matters.
How Early Should You Arrive at LAS?

If you want to avoid a mad dash to your gate, use these guidelines:
- Domestic flights: Arrive 2 hours before departure.
- International flights: Arrive 3 hours before departure.
You might wonder, “Is this overkill?” Not at LAS. Here’s why:
- Parking can take longer, especially in high season or during big events.
- Getting from your car or rideshare to the right terminal sometimes means long walks.
- Check-in, bag drop, and security lines often build up all at once.
- Busy times include 5–8 a.m., 3–6 p.m., weekends, and days when Las Vegas hosts conventions, UFC fights, or concerts.
Tip: Use the MyTSA app or LAS airport website to check real-time security wait times. But always allow an extra buffer—unexpected crowds pop up fast in Vegas.
Important: Double-check which terminal you’re flying from—Terminal 1 (mostly domestic) or Terminal 3 (international and several domestic airlines). There’s no quick connection between them, so hitting the wrong terminal can cost precious time.
TSA Screening at LAS: What to Expect in 2025
The TSA keeps updating its tech to move people and boost security at LAS. Here’s how it changes the process for you:
- Credential Authentication Technology (CAT-2): These checkpoints scan your ID and quickly check flight details, plus optional facial comparison (you can opt out without penalty). There’s no need to hand over your boarding pass, just your ID.
- CT Scanners for carry-ons: Many security lanes use these systems to scan your bags in 3D. Most of the time, you don’t need to remove laptops or small liquids from your bag. Still, put everything in the bins.
- Self-Screening: If you’re TSA PreCheck and flying certain airlines from Terminal 3, you may be invited to try the new self-screening system. Scan your ID, step into a scanner, follow simple video instructions, and only interact with staff if you have a problem. This can save serious time.
REAL ID Requirement: Starts May 7, 2025
Everyone 18 or older must show a REAL ID-compliant driver’s license (gold star on the card) or another acceptable ID to fly. Standard driver’s licenses without this marker won’t work.
Other valid IDs include:
- U.S. passport or passport card
- Global Entry, NEXUS, or SENTRI card
- U.S. military ID
- DHS trusted traveler cards
- Permanent resident card
- Foreign government-issued passport
If your REAL ID doesn’t scan or you don’t have one, you may have to answer questions to verify your identity; failure means no entry through security. Always bring a backup if you can.
Be Patient and Keep It Moving
Screening lines grow fast during peaks. Being calm, prepared, and polite helps everyone—TSA staff included.
Packing and Liquids: Simple, Smart, and Safe
Packing right saves you headaches and money:
- Follow the 3-1-1 rule: Bottles must be 3.4 ounces (100 ml) or less. Fit them all in one quart-size clear zip bag.
- Put all liquids, gels, and aerosols in your checked bag if they’re over 3.4 oz.
- Exemptions: Medications, baby formula/breast milk, and liquid foods for infants are allowed. Declare them at security.
- Start with an empty bag; double-check all pockets to avoid banned items like sharp tools or sports equipment.
- Don’t wrap gifts—security may need to open them.
- Lithium batteries (for phones, laptops, chargers): Carry them on, never check them.
Packing Checklist For Security:
| Required for All Bags | Allowed in Carry-on Only | Declare at Security |
|---|---|---|
| 3.4 oz or less liquids (in bag) | Lithium batteries | Baby formula, breast milk |
| Food (solid only) | Electronics (laptops/tablets) | Medications (liquid/gel) |
| Clothes/shoes | Small travel liquids | Medical liquids |
Expedited Options: TSA PreCheck and CLEAR Plus
Both programs can help you fly through even the thickest security crowds:
- TSA PreCheck: Members keep shoes, belts, and light jackets on. Laptops and compliant liquids stay in the bag. PreCheck lines often move in under 10 minutes. Cost is about $78 for 5 years after a quick background check and fingerprinting. Remember to enter your Known Traveler Number (KTN) when booking.
- CLEAR Plus: Uses biometrics (fingerprint or iris scan) to verify your ID fast. Then, a CLEAR rep escorts you to the front of the TSA screening line. You still need PreCheck for faster screening itself. Cost is about $189/year but can pay off for frequent travelers.
| Program | What You Skip | Cost | Where Offered |
|---|---|---|---|
| TSA PreCheck | Most line hassles, shoes off, laptop/liquid removal | $78 (5 yrs) | Most US airports |
| CLEAR Plus | ID check line | $189/year | Selected airports |
Enroll online or at airports. TSA PreCheck is best for most travelers, CLEAR for frequent flyers or business travelers.
Extra Tips for Stress-Free Airport Travel
Simple steps save you time, money, and stress:
- Wear slip-on shoes and avoid belts or jewelry with metal.
- Keep your ID and boarding pass in an easy-to-reach spot.
