Just to let everyone know. We checked in at LAX and were told that we could use the One World lounge at Tom Bradley. Once we arrived at the lounge the staff stated that we could not use the lounge because Mexicana had their own lounge and that they do not pay the One World lounge for our access and that we should try Mexicana's lounge.

We went downstairs to Mexicana's lounge and were told we would not have access there unless Mexicana gave us a little card which stated we have acess to their lounge.

So, in the end we were not able to access either lounge, and it was getting late, so we just went to the gate. Mexicana's Employees just don't seem to know exactly what they are doing.

In Mexico City we had no problem accessing the lounge.
