Cheap flight from San Francisco to San Diego from $29

The nonstop flight lasts approximately 1.5 hours and covers about 450 miles. There is no time difference to be concerned about because both cities are in the Pacific Time Zone.

The majority of flights take off from San Francisco International Airport (SFO), but if you're in the Bay Area, Oakland (OAK) is also a practical choice. San Diego International Airport (SAN), which is close to the city center and the waterfront, is where you will land.

Are you trying to find some comfort? If you're looking for a more laid-back flying experience, Alaska Airlines and Delta have first-class seats and early boarding. On a tight budget? Southwest is a well-liked, inexpensive choice, but to get the greatest deals, make your reservation directly on their website. If you don't mind paying more for seats and bags and fewer extras, Frontier Airlines is even more affordable. Do you like something in the center? Hawaiian and United Airlines both provide good service at affordable costs. Hawaiian even makes the journey a little more pleasurable by introducing some island-style friendliness on the mainland route.

Airport in San Francisco

San Francisco Bay Area has three major airports serving different travel needs. The primary international gateway is SFO, while OAK serves both domestic and limited international routes.

San Francisco International Airport (SFO)

Location: 8 miles south of downtown.
As the Bay Area's largest airport, SFO accommodates most international flights with 4 modern terminals(1, 2, 3, and International). Direct flights from Phoenix arrive here multiple times daily, with carriers like Southwest, United, and American offering frequent service. The airport's BART station provides direct rail access to the city.

Getting from SFO to Downtown

BART: fastest and reliable ($10.35, 30 minutes to downtown)
Rideshare: typically $40-60, takes ~20mins, depends on traffic.
SamTrans: slow but budgetable ($2.50, 45 mins)

Oakland International Airport (OAK)

Location: 18 miles east of downtown.
Primarily serving domestic routes, airlines like Southwest and Spirit always fly out of OAK. While farther from the city center, its BART connection makes it easy too access.

Getting from OAK to Downtown

BART: $4-5, includes a short transfer at Coliseum Station (12 minutes to city)
Rideshare: $45-60, time depends on the traffic

Airports in San Diego

San Diego International Airport (SAN) is the primary commercial airport serving the city of San Diego. A few international routes (mostly to Mexico and Canada) and the majority of domestic flights are handled by SAN, but other international connections, particularly throughout Latin America, are available at adjacent airports like Tijuana International Airport (TIJ), which is reachable by the Cross Border Xpress (CBX).

International Airport in San Diego (SAN)

Only three miles northwest of San Diego's downtown is the location.

SAN is a small, effective airport that serves both domestic and a few international routes. It has two facilities, Terminal 1 and Terminal 2. Regular flights from San Francisco arrive here on American, Alaska, Southwestern, and United. Because the airport is so close to the city center, transfers are easy and quick.

Getting from SAN to Downtown

Ridesharing/Taxi: Quick and practical. It takes roughly 10 to 15 minutes, depending on traffic, and costs about $15 to $25.
The MTS Route 992 bus is reasonably priced at $2.50, takes 25-30 minutes, and stops at important downtown destinations.

Best Time to Go to San Diego

With warm, sunny weather and less tourists, March through May and September through November are the ideal times to visit San Diego. Comparing these months to the busiest summer months, there are less tourists and nicer temperatures.

While beach vacations are popular from June to August, be prepared for increased crowds and higher hotel rates. Moreover, be on the lookout for "May Gray" and "June Gloom," when cloudy mornings may result from coastal fog. Even though it can rain occasionally, winter (December to February) is a wonderful season to travel if you want to avoid crowds.
