On the South side of LAX sits this awesome museum which is a must if you are into aviation history. The former charter terminal is now a shrine for the good old days. Pan Am, TWA, Western and many more - every airline has its own section with a display of uniforms, model aircraft, seats, photos, timetables etc. over time. You can also have a look at a DC-3 or do research in the library. And there is no spot at LAX where you will get closer to the South runway for plane spotting than at this museum. Best of all - it is free.
