Cheap flights from San Francisco to Gdansk

December comes out cheapest on this route, though the days around Christmas and New Year are the busiest of the year, so if that is your window, book months ahead. Late autumn and early spring are the calm stretches, with thinner crowds in Gdansk and easier connections through the European hubs. Midweek departures from San Francisco are quieter than Friday and Sunday, and Tuesday and Wednesday flights often have the most room. Summer is peak on both ends — Polish school holidays and the US vacation season fill the planes — so lock those dates in early. Flying on the holiday itself can be calmer than the days just before it.

Every airline selling this route is full-service, so what separates them is where you connect and what your ticket includes. Delta Air Lines, United Airlines and Alaska Airlines cover the US side, usually routing you through a hub before the Atlantic crossing. Air Canada sends you north through Canada, while Finnair, Scandinavian Airlines and Swiss connect via their Nordic and Alpine hubs. Air France and TAP Portugal route through Paris and Lisbon. LOT Polish Airlines is the natural choice for the last leg into Gdansk, often via Warsaw. Baggage follows each carrier's own fare family, so check your specific ticket rather than assuming.

Gdansk Lech Walesa Airport is the only airport serving the city, and it sits a short drive from the centre — close enough that a taxi or ride-hailing car gets you to the Old Town without much fuss. A train line links the terminal with the main station, and buses run into town as well, both useful if you land during the day. Late arrivals are the thing to watch: the last trains and buses go early, so check the timetable before you pick a flight that lands after dark. Taxis and app-based cars wait outside arrivals, so use the app or agree the route to avoid any surprises.

Country facts: Wikidata

• Check that your ticket leaves from San Francisco International, since the city has no second airport to fall back on.
• Confirm what baggage your booking includes, because on a connecting itinerary each carrier in the chain can set its own allowance.
• If you book the legs separately, leave a long buffer in the European hub in case the first flight runs late.
• Make sure your passport and any entry documents for Poland are valid before you book.
• Decide whether December suits your plans or whether calmer spring weather is worth the wait.
• Compare total travel time, not just the first leg, since some connections add a long layover in a hub.
