California - LAX Transfer T1 - T5 9:00PM

Need to transfer from T1 to T5 on a Tuesday evening. Have 60 minutes. Can it be done? Is it better to walk or take bus? If walk do I go to arrival level, departure level or cut through parking lots P1 and P7? If bus can I catch one on the departure level or do I need to go down to arrivals?

Thanks.

Do *not* waste time waiting for a bus to come around.
Go to the arrivals level and walk across the parking structures to T7. Hang a right and walk down to T5. You'll go back inside on the arrivals level and head up to security.

I have also bounded across the parking rooftops! Def walk, though.

I wonder how many people have taken cabs from one terminal to another... and how much it costs...
