Give yourself plenty of time (several hours) if you're connecting to a different airline. You have to go out of the airport, take a bus to your terminal, and go back through security to change carrier
To the person who added the tip originally and the 347 (and counting) people who voted for the tip - "Don't get on Oceanic 815" - that flight was routed FROM Sydney TO Los Angeles.
LAX is soooo slow. Don't leave your house to pick someone up until their flight lands. Better them waiting for you instead of you waiting at the curb for them!
If you are flying Virgin America and want to get on a earlier flight with stand by. Remember they charge $25.00 if the flight is not the flight right before your original flight.
If you have a disability do not use the special services line to check in like Delta recommends. It takes way longer to get through the line and is absolutely not worth it!
Why is everyone complaining? If you get here early and aren't an idiot you can make it through this experience just fine. It's just like any other major airport.
TSA at the pre-check at T6 may be the most unprofessional agents of all time, one supervisor even had a fit and attempted to help me miss my flight, sorry buddy, but I made it...
