Do You Have to Go Through Security Between Terminals at Lax

There are no physical airside connections between any of the other terminals. Inter-terminal connections between terminals 1, 2, and 3, and between them and the other terminals, require passengers to exit security, then walk or use a shuttle-bus to get to the other terminal, then re-clear security.

How do you get between terminals at LAX?

You can get between LAX terminals by riding the free landside terminal shuttle bus that runs in a clockwise loop, or by walking on the sidewalks. Terminals 4 to 8 are connected by a series of airside walkways, and Terminal 4 is linked to the International Terminal B via a connector bridge.

Is 1 hour enough for connecting flights in LAX?

The published minimum connect time is 1.5 hours (which I think is still too short). If the airlines re-timed their flights after you booked, they are obligated to change your booking at no cost to you. They cannot force you into a connection that you will knowingly miss.
