How far is the Amtrak or UNION station from LAX airport?

I wanted to take a bus to LAX for my trip this summer. However, I do not have a way there or back and found out that I can take the Amtrak bus who picks up in the union station. Since i'm clueless about the are, I was wondering if I could just walk there or do I have to take a bus to the union station?? THANKS!

LAX to Union Station Flyaway: Starting July 1, the fare is $4. Buses run every 15 minutes. Commute time is 35-60 minutes. Look for the green Flyaway sign on the lower level bus medians. This is the cheapest way and most direct way to get the 20 miles to Union Station.

It's just a little less than 25 miles, but sometimes it takes well over an hour to drive there because the traffic is BAD.

A bus takes carpool lanes, so it goes faster than a car, if you drive alone and cannot take a carpool lane.

I work at LAX. It is about 25 miles from LAX to Union Station. There is a bus that costs $3.00 called the Flyaway Union Station that runs between the two places. It runs about every 30 minutes. If you need more help contact me at: kingsleydr60@yahoo.com I will be happy to help if I can.
