How this was worked out
- FlyerIntel cannot currently obtain live security wait times for LAX, so this figure does not account for the queue on the day.
- It does not include your journey to the airport, parking, or a shuttle from a remote lot.
- International departures, and travel with children, checked pets or special assistance, need more time.
