Flyaway Bus

The Flyaway Bus, a great way to get to LAX from downtown and back. Costs $4 per person and takes approximately 25 minutes because it uses the carpool and bus only lanes. It stops at Union Station and all the bus islands at LAX with green signs. It runs every 30 minutes. There is longterm parking available for your car at Union Station. Other Flyaway Buses are available for UCLA and Van Nuys. The link above will give you all the details.

We've used the Flyaway Bus a few times now and have been very happy with it, but it is a silly name.
