LAX certainly has the worst of the CX lounges that I have visited. For starters, it is way too small for the number of Business and First passengers that need to be accommodated. There are no showers, no bathrooms and no internet terminals. It has self-serve complimentary drinks, sandwiches, packaged snacks and sometimes fruit, so it is better than waiting in the terminal, but that's about the best I can say for it.
The First Class section is truly a joke. It has smoked glass doors that open automatically as you approach to reveal (drum roll please) ....
a very plain room that is about 10' x 12' with a dozen wing back chairs crammed in so tightly that the armrests touch each other, a coffee table and a TV. That's it.
