TSA at Airports in the USA — Security Check, REAL ID, PreCheck, Global Entry (2026)

TSA (Transportation Security Administration) controls all passengers at American airports. Average screening time: 15-45 minutes during peak times, longer during holidays. This guide explains how it works, what you can/must do, and how to skip lines through PreCheck / Global Entry.

REAL ID — KEY from May 7, 2025

From May 7, 2025, all domestic flights require:

• REAL ID compliant driver's license / state ID (with a star in the corner)
• OR U.S. passport
• OR Permanent Resident Card (Green Card)
• OR military ID
• OR tribal ID
• OR Enhanced Driver's License (MI, NY, VT, WA, MN)

Without REAL ID or equivalent ID = NO BOARDING.

What if I only have a standard driver's license (non-REAL ID)

• Go to the DMV and upgrade to REAL ID
• Requirements: passport / birth certificate + SSN card + 2 proofs of address
• Cost: $0-15 typically
• OR: fly with a Polish passport / Green Card

TSA Standard — What to Expect

Step 1: Document Check

• You show ID + boarding pass
• TSA officer scans both
• Checks name match
• IMPORTANT: the name on the ticket MUST exactly match the ID. A typo = problem.

Step 2: Body Scanner

• Stand in the scanner, hands above your head
• 5 seconds
• Alternative: pat-down (if you refuse or the system selects you)

Step 3: Bag X-ray

• Carry-on goes on the conveyor
• Shoes, belt, phone, keys, laptop, electronics in a separate container
• (PreCheck = you do not need to remove)

Step 4: After Screening

• Gather your belongings
• Put on shoes, belt
• Pack laptop
• Go to the gate

• TSA may test separately

Syringes / needles

• OK with a prescription
• Show TSA

CBD / medical marijuana

• FEDERALLY illegal regardless of state
• TSA technically does not check but if found → may call the police
• DO NOT FLY with marijuana between states

Special Situations

Polish Passport — without REAL ID

A Polish passport DOES NOT work as REAL ID. But it works as a document for all flights (domestic + international). You can show a Polish passport instead of REAL ID.

Without ID

If you lost your ID:

• TSA may allow you after additional screening
• Pat-down, additional questions
• Accepted: credit card, Polish ID, college ID
• May add 30-60 minutes to your process

Religious Head Coverings

• Hijab, turban, kippah: OK, you can wear through the scanner
• TSA may request a pat-down but you can ask for a female officer / private screening

Disability

• Wheelchair — through an alternative scanner
• Medical implant — show documentation
• Service animal — requires documentation

Common Mistakes

1. No REAL ID / passport in 2025+ — will not be allowed
2. Liquids > 100 ml in carry-on — will be discarded
3. Not turning off laptop before screening
4. Name on ticket ≠ ID — denial
5. No PreCheck despite qualification — waste of time
6. Late arrival — minimum 2h before domestic flight, 3h international
7. Packing prohibited items in carry-on (knives, weapons)
8. Ignoring 3-1-1 rule for liquids
9. Bringing power bank in suitcase — FAA forbids

Final Tips

• Arrive early — 2h domestic, 3h international
• Pack wisely — boots, beret, jacket easily removable
• Small cash separately — you can change at kiosks
• Charged phones — TSA may want to demonstrate it works
• Layered clothing — easy to remove
• Bidet bottle / hydroflask — empty through screening, fill afterward
