We just went about 2 weeks ago and used Uber to and from LAX to Paradise Pier. It was about $55 each way, not including tip. Super affordable for us. Like someone else mentioned, you have to ride the shuttle to the Uber/Lyft/rideshare lot to be picked up but they can drop you at your terminal for the return trip. Look for the green LAXit signs to get the shuttle (there was a huge line when we were there but we got on the first one). It was all super easy! Not sure if you're staying at Paradise Pier, but drop off was quite confusing for us but we figured it out. I recommend Uber/Lyft for sure!
