I've thankfully mostly avoided LAX for the past several years, and I have never been in terminal 5. But I have a trip departing from there in a few days, and I'm trying to figure out if there are any lounges I can reasonably access airside with Priority Pass, Amex Platinum, or United Club membership. I know there's the Admiral's Club in T5, but I unfortunately got rid of my Citi AAdvantage Executive card a couple of years ago, so I don't have access (and I'm not sure I care enough to pay for a day pass for both my wife and myself).

Any suggestions?
