The airport is easy to navigate with clearly marked signs
San Francisco International Airport (SFO) is one of the largest and busiest airports in the country, but it is not difficult to navigate. The airport has clear signage to help passengers find their way. The airport is circular, with the terminal boarding gate areas outside the circle and parking and ground transportation on the inside. The airport has one international terminal (with two concourses) and three domestic terminals, easily reached via pedestrian walkways or by riding the AirTrain. The AirTrain connects all terminals, the rental car station, and the BART train, pre-security.
Regardless of which terminal you arrive at, there are several clearly marked signs to help you navigate the airport. If you don't know your departure gate, you can refer to the large arrivals/departures signs positioned at many locations within the airport. If you're still unsure, you can ask for assistance at information desks or from airport/airline staff or even fellow passengers. Once you know your gate, you can follow the large overhead signs to your destination.
If you're driving to the airport and parking your car on-site, you can save money by taking the BART train and leaving your car at home. The BART conveniently connects SFO to downtown San Francisco, so there's no need for an expensive taxi ride or sitting in traffic.

SFO is prone to San Francisco's fog, which can cause delays
San Francisco International Airport (SFO) is one of the largest and busiest airports in the country, with 57.8 million passengers travelling through it in 2018. Despite its size, SFO is not difficult to navigate. All of the terminals, the rental car station, and the BART train station are connected by an easy-to-use air tram.
However, SFO is prone to San Francisco's legendary fog, which can cause delays. When visibility is reduced, SFO can only use one of its two runways, which can cause delays as flights wait for the fog to lift. In fact, SFO can sometimes be the only foggy spot on the bay.
If you are concerned about potential delays, there are alternative airports within a reasonable distance of San Francisco that may be more convenient. Oakland International Airport (OAK) and San Jose International Airport (SJC) are both within easy reach of San Francisco and experience fewer delays due to their less foggy locations. Oakland is just a 40-minute ride away via the BART, and San Jose is accessible by CalTrain, with a change at Millbrae.
If you are flying into or out of SFO, it is worth checking which terminal your flight is departing from in advance, as this can save time and effort. You can find this information on the 'Airlines at SFO' page of the airport's official website.

Oakland and San Jose airports are reasonable alternatives to SFO
San Francisco International Airport (SFO) is a major hub for United Airlines, with almost 300 daily flights around North America and 30 international destinations. It is also the Bay Area's largest airport and one of the largest hubs on the west coast. However, if you're looking for alternatives to SFO, Oakland and San Jose airports are reasonable options.
Oakland International Airport (OAK) is a smaller airport located across the bay in Oakland. It is technically an international airport, but almost all of its flights are domestic, with the longest routes being about five hours. Oakland is easily accessible from San Francisco via the Bay Area Rapid Transit (BART) system, which costs $8.50 per person one-way and takes around 45 minutes. However, getting to Oakland from Fisherman's Wharf, a popular tourist attraction, requires changing trains three times, which some may find inconvenient.
Norman Y. Mineta San Jose International Airport (SJC) is another alternative to SFO. It is one of the fastest-growing US airports and the second busiest in the Bay Area. While it is primarily a domestic airport, there are a few select international destinations in Asia, Canada, Europe, and Mexico. San Jose Airport is extremely close to downtown San Jose, and an Uber or taxi ride will be fairly cheap and quick. However, getting from the airport to San Francisco can be time-consuming and costly, with rideshares and taxis costing up to $150.
In summary, Oakland and San Jose airports offer reasonable alternatives to SFO for travellers looking for different options or flight routes. Oakland is a good choice for those who prefer smaller airports and primarily domestic flights, while San Jose offers a balance of domestic and select international destinations. Both airports are accessible from San Francisco, but travellers should consider their specific destinations and preferred modes of transportation when deciding which airport to choose.
