Cheap flights from San Francisco to Warsaw

March is the cheapest month on this route, sitting in the quiet stretch between the winter holidays and the spring rush. Summer is the busiest and priciest time, with July and August filling up early, so book well ahead for those weeks. Late September and October are a good compromise: mild weather in Poland, thinner crowds and more reasonable fares. Midweek departures usually cost less than Friday and Sunday flights. Watch the Polish holidays at the start of November and the Christmas period, when seats home fill fast. Booking a few months out generally beats waiting.

Every carrier on this route is a full-service airline, so there is no low-cost option to weigh against them: Alaska Airlines, LOT Polish Airlines, Austrian, TAP Portugal, Brussels Airlines, Turkish Airlines, Aer Lingus, Air Canada, British Airways and United Airlines all sell seats here. Direct flights are available, and the rest of the list connects through each airline's own hub, which usually means a longer journey but sometimes a better fare. What you get on board depends far more on the fare family than on the airline: the cheapest economy tickets often exclude a checked bag and seat selection, while flexible fares include them. Compare the total, not just the fare.

Warsaw has two airports. F. Chopin is the main one and sits close to the city centre, with a short ride by train, bus or taxi into the middle of town. Modlin sits further out to the north, and getting in means a bus or a train connection, which takes considerably longer, so factor that into your plans. Check which airport your ticket actually uses before you book, because the two are not interchangeable and a late arrival can leave you with few options into town. If you land at Chopin, the train and the bus both run to the centre; taxis and ride-hailing are easy to find at either airport.

Country facts: Wikidata

• Which Warsaw airport your flight uses, since F. Chopin and Modlin sit on opposite sides of the city and are not interchangeable.
• Whether your fare includes a checked bag, because the cheapest economy tickets on this route often do not.
• Whether a connecting itinerary is on one ticket or separate ones, since separate tickets leave you carrying the risk of a missed connection.
• Passport validity and entry rules for Poland, including whether you need a visa or proof of onward travel.
• How your travel dates line up with Polish holidays and the summer peak, when seats sell out early.
• Total journey time, because a cheap connection can add many hours to a long trip.
