The total flight time between these two cities is nearly one and a half hours. It is a fast way to travel between San Diego and San Francisco, even if you add some check-in and baggage clearance hours.

Southwest Airlines is a popular option for this trip, with no baggage fee and no change fees. You’ll get the lowest rates from them if you reserve at least a couple of weeks ahead of time, but you’ll have to go to their website to do it – they don’t participate in other websites’ fare searches.

2. San Diego to San Francisco Drive by car

The distance between San Diego and San Francisco is nearly 500 miles. So, if you are lucky enough to find no traffic jams, it will take you around 8.5 hours to get there.

The California freeways have so many options to travel between San Diego and Los Angeles that it would take you the same time to select a route as it would take to drive it. I’ve made this trip many times and can help you narrow down the options to just a couple.

If you want to travel this long journey from San Diego in one day, you have to reach Los Angeles as fast as you can.

Most online mapping sites will route you through Los Angeles on Interstate Highway 5, but that freeway can be more than frustratingly jammed up, adding more than an hour to your trip, even when it isn’t rush hour.

Traffic jams can happen anytime on any road, so it’s best to check the current traffic situation before setting out to ensure it’s the optimum route at that time. If you don’t have a mobile device that provides traffic info, Los Angeles radio station KNX 1070 has frequent traffic updates.
