LAX Connection

[CPT Trips]

We will fly from PHL to LAX (AA) to connect with Qantas to Australia. Is it likely that we will need to go through security in LAX, or is there a way to stay inside security?

TIA

[Critically Cruising]

The AA terminals and the TBIT are all connected airside.  No additional screening needed as long as you don't leave the sterile area.  Look for the signage.

If you walk towards security you'll see the escalators to TBIT off to the left. 

 

If you're in First/have Emerald status you'll see the First Lounge on your right almost behind after you've taken the escalator and moving walkways before you get into TBIT proper.
