No better time to pop your Uber cherry
You can download the app and play around with it to familiarize yourself. Its quite easy to use. Uber has been around a while in CA and is very commonly used. I would have no hesitation about using it there, especially for the first time. There should be a ton of drivers in the area of the airport, so once order one, my guess is one will be there within 10 minutes or less to pick you up. The app will tell you where to go to meet them at the airport. It should cost roughly $50 one way and you will be the only passenger.
