Driving from San Diego to Los Angeles
Using either of the driving routes below, you'll encounter a Border Patrol checkpoint along the way. Run by the Immigration and Naturalization Service, they are only on the northbound side of the highway, and according to the INS website are directed against "smuggling of illegal aliens and narcotics away from the border area." Most vehicles are waved straight through, but on busy days, there can be delays.
Before you set out, it helps to know the local lingo. Use the Los Angeles driving guide to find out what a SigAlert is, rules for Los Angeles carpool lanes and to see an LA freeway map.

Flights from San Diego to Los Angeles
Travel Time: Flight time between San Diego and Los Angeles is less than 50 minutes. If you could hop on and hop off the plane with no waiting, it would be the fastest way to go. But getting to the airport early to check in and collecting your bags on arrival makes the journey last closer to 2.5 hours.
You'll get the cheapest tickets - no matter which airline you choose for a flight from San Diego to Los Angeles - by planning at least two weeks in advance and you might save more if you do that a month ahead of time.
When looking for a flight, if the time seems too long, you're likely to take a scenic tour of more than one airport along the way (otherwise known as a multi-stop flight). And oddly, the airlines tend to charge more for taking twice as long to get you to your destination.
Several airlines offer flights between San Diego and LAX, but as of early 2017, Southwest Airlines doesn't fly direct from San Diego to LAX, Orange County or Long Beach. Instead, they fly to the Burbank Airport, which is a short drive from downtown Los Angeles and close to public transportation.
You won't find Southwest on any of the online travel sites. Check airfare directly with their website, where you can also find hotel and airfare packages that can make planning your trip quick and easy.
The three-letter code for the San Diego airport is SAN. Los Angeles is LAX, Long Beach LGB, Orange County SNA and Burbank BUR.Continue to 3 of 3 below.

San Diego to Los Angeles by Buses or Train
If you want to get from San Diego to Los Angeles (or vice versa) without renting a car and driving, the previous page describes flight options. If you want to keep your wheels on the ground instead, try a bus or train.
San Diego to Los Angeles by Bus
Greyhound runs from San Diego to Los Angeles several times a day. The fastest trip is a little more than 2 hours and fares are lower than flying.
Flixbus also offers bus service between Los Angeles and San Francisco. On the LA end, they stop in five locations, including some on the Westside. In the San Diego area they stop in La Jolla, Mission Valley, and downtown.
San Diego to Los Angeles by Train
The high-speed rail system you may have heard about between San Diego and San Francisco is unlikely to ever happen, according to California Governor Gavin Newsom who said in his 2019 State of the Address “Right now there simply isn’t a path to get from Sacramento to San Diego—let alone from San Francisco to LA," but you can make the trip on Amtrak.
The Amtrak Pacific Surfliner takes about 2.5 hours to travel from San Diego's Santa Fe Depot to Union Station in Los Angeles, stopping in several Orange County cities (including Anaheim) on the way to downtown Los Angeles. From there, it goes on to Glendale, Burbank and the San Fernando Valley.
If you choose to travel by Amtrak, they have two stations in San Diego: Old Town and downtown, which their website lists as "SAN" (which could be easily confused to mean the San Diego Airport, which uses the same initials).
Once you reach Orange County on Amtrak, you can transfer to Metrolink which runs several lines throughout the Los Angeles area. From Union Station, the LA Metro system trains go to many locations as well.
Here's a fun fact: Los Angeles' Union Station is known as the "Last of the Great Railway Stations" and was placed on the National Register of Historic Places in 1980. If you enjoy watching movies or TV shows, chances are you will recognize the place from one of its' many appearances on the screen.
