Cheap flights to San Francisco should be available on some of the many domestic and international airlines which serve San Francisco International Airport. It's a major west coast hub, like Los Angeles.
For anyone planning to drive the Pacific Coast Highway, a cheap flight to San Francisco is a good starting point, if you can get one. Low-cost airlines flying to San Francisco include Southwest Airlines, SkyWest, Virgin America, and JetBlue. Just a few of the many major international carriers are Air Canada, Air China, Air France, Air New Zealand, British Airways, KLM, Lufthansa, Qantas, and Virgin Atlantic. Major US airlines flying into San Francisco include American Airlines, Continental, Delta, United Airlines, and US Airways.
San Francisco airport (code: SFO; tel: 800/435-9736 or 650/821-8211; website: http://www.flysfo.com) is ideally located for driving south down the Pacific Coast Highway. It's right on Highway 101, near the junction with Highway 380, about 13 miles south of the city center. Rather than take 101, though, we recommend taking 380 then 280 North, then take Exit 47 onto CA-1 South, cutting across to the coast to start your Pacific Coast Highway drive that way. It should only be a 15-20 minute drive and you'll be seeing the ocean, and there are plenty of car rental places at the airport if you want to collect a hire car there.
Many international airlines use San Francisco International, which increases the chance of finding a budget flight bargain. In addition to the airlines mentioned above, some of the other international carriers are Air Berlin, Singapore Airlines, the Central American airline TACA, Swiss International Air Lines, Philippine Airlines, Aeroméxico, Mexicana, LAN Peru, Korean Air, Japan Airlines, All Nippon Airways, Emirates, EVA Air, Cathay Pacific, and Asiana Airlines.
As well as Air Canada, there are seasonal low-cost flights on WestJet to San Francisco from Calgary, Edmonton, and Vancouver.
Some of the best options for cheap flights within the USA will be with Southwest Airlines, who fly to San Francisco from Chicago, Denver, Las Vegas, Los Angeles, John Wayne Airport in Orange County, Phoenix, and San Diego.
Other budget air fares may be available through the following airlines, though some routes only operate seasonally:
AirTran Airways, who fly to San Francisco from Atlanta and Milwaukee.
Alaska Airlines, flying not only from Anchorage but also Palm Springs, Puerto Vallarta, San José del Cabo, and Seattle.
Frontier Airlines, from Denver and Milwaukee to San Francisco.

Other airlines flying the route and who might be worth checking for special offers are American Airlines and United.
