Hi flyertalk gurus! My family and I were scheduled to travel today to Puerto Vallarta from LAX on Mexicana. It turns out my passport was expired -- so my family is en route and I'm waiting for my passport now. The office says it should be ready this afternoon, so what I need help with is advice on how best to get to Puerto Vallarta. There is a flight tomorrow morning, LAX->Puerto Vallarta at 9:55am PST, which is the same one I was supposed to be on today -- but the flight is full.

Is my best bet to get to the airport at 5am and try to get on it standby? Thanks in advance for all your help, your assistance will make mine a much happier holiday!!
