Be at LAX two hours before a domestic departure and three before an international one.
A maps app covers the drive to LAX. Bag drop, security, and the walk to your gate usually take longer, and they are the steps people misjudge.
Here is the same plan drawn to scale. The first block is travel; the next two are the airport. A checked bag grows one, a far gate grows the other.
Front door to boarding: 3hr
Be at LAX two hours before a domestic departure and three before an international one. At an airport this size, treat those as a floor. They assume a normal day, not a holiday crush or a long security line.
The horseshoe loop in front of the terminals can add half an hour at peak, so put buffer on the road rather than only at the curb. Know your terminal letter before you enter the loop: getting dropped at the wrong terminal before security costs you the most time, while most terminals connect on foot once you are through it.
Almost every terminal has its own checkpoint (Terminal 2 screens at Terminal 3; Terminal 5 closed for reconstruction until 2028). Know your terminal before you leave: fixing a mistake means the loop, a shuttle, or a long walk. Where corridors connect, clearing at a quieter terminal and walking is sometimes an option.
The plan allows 30 minutes for a standard lane on a busy but normal morning. With TSA PreCheck, that drops to 15 minutes. A checked bag lengthens the one before it.
LA traffic is the wildcard: maps times can change by 20 minutes between check and leave. Bag check and rental return add time; rideshare uses a dedicated lot. FlyAway from Van Nuys and Union Station, or Metro C/K to the LAX/Metro Transit Center with a free shuttle to every terminal.
For live waits, parking, and terminal maps, check the official LAX site.

Be at LAX two hours before a domestic departure and three before an international one. At an airport this size, treat those as a floor. They assume a normal day, not a holiday crush or a long security line. The plan above works back from there through security, bag drop, parking and the drive to a leave-by time.
The plan allows 30 minutes for a busy-but-normal standard lane. With TSA PreCheck it drops to 15 minutes, and you can edit either one to what you actually see. A checked bag lengthens the step before it. Checkpoint detail for LAX is under Security at LAX above.
Earlier than for a domestic one. International boarding starts 45 minutes before departure instead of 30, which pulls every step earlier. Use the airline desk for bags: documents get checked and counters often close an hour out. That also covers lap infants, unaccompanied minors, and oversized bags. If your boarding pass names a boarding time, match that.
Work backward from departure: boarding, time at the gate, the walk, security, bag drop, parking, then the drive (45 minutes in the default plan). Replace the drive with your own route. The leave-by moment is the first travel row, "Drive to LAX" by default.
Taking the train instead? The Amtrak station pages use the same kind of plan without security. Flying from somewhere not listed? The airport leave time calculator has the same rows with your own numbers, and the wake-up time calculator runs it back to the alarm.
Start the plan in the app, and the Lock Screen and Dynamic Island show the time left, with a bar that fills as each step passes.
Glance at it in the terminal without opening the app.
Every step also gets its own alert, and sharing the plan gives whoever is driving the same leave time, with alerts on their phone.
