I will be arriving on AA72 from SYD into LAX TBIT and then have a connecting AA flight out of T4 to SJC/ORD. I will have checked bags. After clearing custom and PP control, rechecking my bag, can I then use the QF First Lounge in TBIT? I am QF Plat. I have about 3.5 hours, and would prefer to use the First Lounge and not the AA T4 lounge. Any ideas??
