If you are taking a trip to Los Angeles, you will undoubtedly be going through the Los Angeles International Airport. The Los Angeles Airport (which is commonly referred to as LAX) is one of the largest airports in the United States. Throughout the course of each year, LAX is responsible for handling a countless number of flights and passengers. Like any airport, the operations at LAX are not perfect, but because they do handle so many flights and travelers every single day, I think you will find that LAX is run much more smoothly than many other smaller airports.
Since you are obviously flying if you go through LAX, you will need to figure out how you are going to get around once you arrive in Los Angeles. While Los Angeles is a large city, it is quite spread out, so getting around in taxis is not really a feasible idea. Instead, the preferred method of transportation for travelers is a rental car. Because LAX is served by over twenty different rental car companies, you should have no problem getting a rental car to use during your time in Los Angeles.
