Common questions

Where can I fly cheaply from San Francisco?
We are currently tracking 1694 fares out of San Francisco across 258 destinations, listed cheapest first above.
Is San Francisco the cheapest airport for this trip?
Not always. Cached fare feeds cover big hubs densely and secondary airports sparsely, so a cheaper nearby airport is often simply missing from a normal search rather than more expensive. Our reverse search prices a whole region's airports against each other to surface it.
