The KAL lounge in TBIT, though a nice space is really lackluster, chips and salsa, a cold pasta salad, and some other basics, poor wine/self service bar. It's pathetic especially since it's Koreans big hub and has many international flights. I'd avoid it. Alaska is a decent lounge that I enjoyed going to when Delta was in T5 and had access with PP or previously with Delta Sky Club membership.

There is a T2 Virgin Atlantic lounge available only in the mornings. Has limited food and beverage offerings unlike when it's closed only to VS pax in the afternoon and evenings which has full bar and table made to order food options.

Given how big the LAX airport is, PP should really get more options that is accessible to each terminal (T1-3 are not connected without a bus)
