I'm looking at option to fly business SYD-NYC on UA in May, so I have a choice of LAX or SFO as transit points. I realise that I'm entitled to Polaris lounge access at my transfer point, so my question is which airport makes that more easy/straightforward, especially if my layover is not super long? As a general rule, I usually prefer arriving into SFO, but I assume that with the Polaris lounge located in the international terminal and my transcon flight departing from terminal 3, would that actually be easier in LAX or are both fine in that regard?
