How Long Is a Safe Layover at LAX for International Connections?
A safe LAX international layover is 2 hours on one ticket, 3 if you change terminals or book separately. Here's why, terminal by terminal.
If you're arriving at LAX from abroad and connecting to another flight, plan on at least 2 hours on a single ticket. Allow 3 hours if you have to change terminals or your flights are on separate tickets. Flying the other way, from a US city out to an international flight, 90 minutes is workable in the same terminal and 2 hours is safer if you change terminals.
These are realistic figures as of October 2026, not the bare minimum an airline will sell you. Here's what fills that time, and why LAX in particular rewards a cushion.
Why international arrivals take so long at LAX
The United States has no "sterile transit." That means there's no sealed-off zone where international passengers can walk from one gate to the next without officially entering the country. Every international arrival at LAX goes through the same five steps, even if you're only in Los Angeles for an hour:
- Clear US immigration. An officer checks your passport and visa or travel authorization.
- Collect your checked bags from the baggage belt.
- Clear customs with those bags.
- Re-check your bags for the onward flight.
- Go through TSA security again before you can reach your gate.
Immigration is the big unknown. The arrivals hall at Tom Bradley International Terminal (TBIT, also called Terminal B) can take anywhere from 30 to 90 minutes at peak. Peak is roughly mid-afternoon into the evening, when long-haul flights from Asia and Europe land in waves.
If your flight also arrives late, a 90-minute connection can disappear before you reach the immigration officer.
Safe layover times at LAX, by connection type
"Minimum connection time" (MCT) is the shortest gap an airline will allow between two flights on one ticket. It assumes everything runs on time. The figures below are more realistic minimums for an average traveler, as of October 2026.
| Connection | Same terminal | Changing terminals | Separate tickets |
|---|---|---|---|
| International → domestic | 2 hours | 3 hours | 3 hours |
| International → international | 2 hours | 3 hours | 3 hours |
| Domestic → international | 90 minutes | 2 hours | 3 hours or more |
| Domestic → domestic | 60–75 minutes (same alliance) | 90 minutes if Terminal 1 is involved | — |
International-to-international connections, such as Tokyo to Mexico City via LAX, go through the same immigration, bags, customs and security steps as international-to-domestic. Budget for them the same way.
If you're nervous, travel with mobility needs, or land at a peak time, add 30–60 minutes to these numbers. Missing a long-haul flight costs far more than an hour in a lounge.
The terminal map that matters for connections
LAX has nine terminals arranged in a horseshoe around a central loop road: 1, 2, 3, TBIT, 4, 5, 6, 7 and 8. What matters is whether you can walk between them without leaving security. "Airside" means behind security; "landside" means the public side, before security.
As of October 2026, airlines are roughly assigned like this:
- Terminal 1: Southwest
- Terminals 2 and 3: Delta (some Delta partners use T2/T3 or TBIT)
- TBIT: most international airlines
- Terminals 4 and 5: American
- Terminal 6: Alaska and some others
- Terminals 7 and 8: United
And here's how they connect airside:
- TBIT and Terminals 4–8 are linked by walkways and tunnels behind security.
- Terminals 2 and 3 are linked to each other and to TBIT by a connector.
- Terminal 1 is not connected to anything airside. Any connection involving Terminal 1, including onward flights on Southwest, means leaving the secure area, walking or riding to T1, and going through security again.
Those airside links only help once you've already cleared immigration and customs. After an international arrival you re-clear security anyway, so the walking distance is usually not the problem. The queues are.
Terminal assignments shift, so check your boarding pass or airline app on the day. Flylax.com has the current map.
Separate tickets: why 3 hours is the floor
On a single ticket, the airline is responsible for getting you to your destination. If your first flight is late and you miss the second, it rebooks you at no charge. Your bags are also tagged through to your final destination, so the re-check after customs is a quick drop at a recheck belt.
On separate tickets, none of that applies. You're a brand-new passenger as far as the second airline is concerned. You must:
- Collect your bags and exit into the public arrivals area.
- Get to the right terminal. The automated people mover, LAX's landside train linking the terminals and the rental-car center, helps here.
- Check in and drop bags at the airline counter before its cutoff. For international departures the cutoff is typically 60 minutes or more before departure; confirm on your airline's site.
- Clear security from scratch.
If you miss the second flight, the airline can treat you as a no-show, and the cost of a new ticket is usually yours.

The rule of thumb: a separate-ticket connection at LAX is only worth it if the savings would cover a replacement fare, or if you can leave 4 hours or more.
How to make a tight connection less tight
You can't control the immigration queue, but you can shorten your part of it.
- Global Entry is a US trusted-traveler program for pre-approved, low-risk travelers. Members use kiosks or a dedicated lane and often skip most of the line. You must apply and be approved well in advance. Our services guides cover trusted-traveler programs.
- Mobile Passport Control is a free government app for eligible travelers, including US citizens. You submit your details on arrival and use a separate, usually shorter, lane. Check on the CBP website whether your nationality qualifies.
- Sit near the front of the plane if you can. On a widebody jet, being off first can put you ahead of hundreds of people in the immigration hall.
- Fly with carry-on only on a single ticket if practical. You still clear customs, but you skip the wait at the baggage belt.
- Have your documents ready. Visitors need the right visa or travel authorization for the US, and for the onward country if it's international. Use our entry-requirements lookup before you fly.
- Track your inbound flight. Use live flight status on the day to see whether your first leg is running late and which terminal and gate you'll arrive at. How to Find the Inbound Aircraft for Your Flight and Predict Delays shows how to spot a late departure before the airline announces it.
When the airline sells you a short connection
Airlines won't sell a single-ticket itinerary below their own minimum connection time. Some of those minimums are shorter than the figures in this guide. A 90-minute international-to-domestic connection may be bookable, but the airline's minimum assumes an on-time arrival and normal queues.
If you're offered two options and one is a 90-minute connection while the other is 2.5 hours, take the longer one for an international arrival. If you do end up on a short connection and miss it, the airline rebooks you on the next available flight. On a busy route, that can still mean a night in Los Angeles.
Frequently asked questions
Is 90 minutes enough for an international-to-domestic connection at LAX?
It can work if your flight lands early and immigration is quiet, but it's risky. Two hours is a realistic minimum on one ticket, and 3 hours if you're changing terminals.
Do I have to collect my bags if my international flight connects at LAX?
Yes. Every international arrival collects checked bags, clears customs, and re-checks them, even on one ticket. On a single ticket the re-check is a quick drop after customs; on separate tickets you must check in again at the airline counter.
Can I connect to a Southwest flight at LAX without leaving security?
No. Southwest uses Terminal 1, which has no airside connection to any other terminal. You'll leave security, go to Terminal 1, and be screened again, so allow about 3 hours after an international arrival.
