TSA PreCheck and Security Checkpoints at LAX
Quick questions about security at LAX
How early should I arrive for security?
3 hours before international flights and 2 hours before domestic flights, as the airport recommends. Add 30 minutes if you arrive by car at peak times.
Does LAX have TSA PreCheck and CLEAR?
Yes. Both are available at LAX checkpoints. With PreCheck you usually keep your shoes on and your laptop in your bag; CLEAR verifies your identity before you reach the officer. Reviews note that CLEAR is not open at every checkpoint at all hours.
What ID do I need?
A REAL ID or another accepted document, such as a passport. Without one, TSA ConfirmID costs USD 45 and is valid for 10 days of travel; allow extra time.
When are the lines longest?
Early morning, midday and evening, when many domestic and international flights leave together. Evenings are especially busy at Terminal B.
Do I clear security again on a connection?
Only if you arrive from abroad or leave the secure area. Domestic connections usually stay inside security. See the connection calculator.

Critical points: smart traveler’s manual
Very uneven lines
User experience:
- Many travelers cleared security in 10 minutes or less, and some call it one of the best TSA experiences in the country.
- Others describe long lines, rude officers and crowded areas with no clear instructions.
- Experiences depend a lot on the terminal and the time of day.
Strategy: Check wait times in the MyTSA app before you leave, and arrive earlier than usual in the evening at Terminal B.
PreCheck and CLEAR in practice
User experience:
- PreCheck members report screening in a few minutes.
- Some reviews mention CLEAR signs that lead to a lane that is closed, and PreCheck lanes where electronics still had to come out.
Strategy: Make sure your Known Traveler Number is on your booking, and ask an officer if the CLEAR lane is not staffed.
Night checkpoints
User experience:
- Some checkpoints close overnight; a review mentions the Terminal 6 checkpoint closed at night, with few seats in the check-in area.
Strategy: On very early flights or overnight layovers, ask your airline which checkpoint will be open.
Pros and cons of security at LAX
- Pros:
- Fast programs: TSA PreCheck and CLEAR save a lot of time.
- Often quick: many reviews report lines under 10 minutes.
- Contras:
- Uneven: long lines at peak times and very different treatment depending on the officer.
- Second screening: international arrivals and some terminal changes require clearing TSA again.
Checkpoints by terminal
Each LAX terminal has its own TSA checkpoint on the Upper/Departures Level. Once inside, the post-security connector lets you walk to most other terminals.
- Terminal 1: Southwest and JetBlue.
- Terminals 2 and 3: unified Delta complex with a shared checkpoint in the central headhouse.
- Terminal 4: American Airlines, connected to Terminal B after security.
- Terminal 6: Alaska and Air Canada.
- Terminals 7 and 8: United.
- Terminal B (Tom Bradley International): screening on Level 4, departures level.
Terminal 5 is closed for reconstruction until 2028. See terminals.
TSA PreCheck, CLEAR and Global Entry
TSA PreCheck
A TSA program for low-risk travelers: separate lanes where you usually keep your shoes, belt and light jacket on and your laptop and liquids in your bag. Membership lasts 5 years; you add your Known Traveler Number to each booking.
CLEAR
A private paid service that verifies your identity with biometrics and takes you to the front of the line. It does not replace screening: combined with PreCheck, you also use the PreCheck lane.
Global Entry
A U.S. Customs program that speeds up immigration on arrival from abroad and includes TSA PreCheck. LAX offers Enrollment on Arrival to finish the interview when you land.
Before you reach the checkpoint
- Liquids: containers of up to 3.4 oz (100 ml) in one quart-size bag (3-1-1 rule).
- Electronics: in standard lanes, laptops and large electronics go in a separate bin.
- Documents: boarding pass and ID in hand; on domestic flights, a REAL ID or passport.
- Locks: use TSA-approved locks on checked bags.
Strategy: After security, find your gate first: some gates are 15 minutes away on foot or reached by bus. See departures.
