I have a 4 hour layover at LAX (hoping to catch the earlier flight via standby) but in case I don't I was thinking of grabbing some in n out and then heading to the TBIT *A lounge. Since I'll need to re-clear security, which terminal is the best to do so at? Can I go through security at any terminal with a UA boarding pass, and if so which one would be best for me, or am I limited to the security checkpoints at T7/T8 and then needing to make the trek back to TBIT.
