Thanks for the suggestions.
I know on an AA ticket you're allowed entry to the TBIT One World lounge, but I was asking about QR since QR has it's own designated lounge in T2 and are not listed on the sign at the TBIT OW lounge.
I'd still appreciate knowing if anyone has experience going to the TBIT One World lounge with a QR business class ticket.
As far as security goes, I'm flying in on AA T4 so can walk over to TBIT airside. I'll have to go out and reenter T2 security when it's time to head over for my flight.
I used to live in LA so I'm well aware of the deliciousness of In-N-Out...not a terrible idea either.
