Cheap flights from Seattle to Warsaw

February is when fares on this route tend to be at their cheapest, and the months around it, from late autumn through early spring, usually stay cheaper than the summer rush. July and August are peak, when school holidays push prices up on both sides of the Atlantic, and December is busy with Christmas travel. Midweek departures, especially Tuesday and Wednesday, are generally quieter than weekend ones. Watch Polish public holidays in spring and the weeks around Thanksgiving in the States, when seats fill faster. Booking a few months ahead gives you more choice of dates and carriers.

There is no nonstop service between Seattle and Warsaw, so every option involves at least one connection, usually through a European hub. Airlines on the route include Iberia, Swiss, Austrian, Aer Lingus, TAP Portugal, Edelweiss Air, United Airlines, Delta Air Lines, Lufthansa and Air Canada. Most are full-service network carriers, where a checked bag and meals are often part of the fare, though light fare types can strip that back. Edelweiss Air sits closer to the leisure end, with a simpler cabin. Where you connect matters: a stop in Lisbon, Dublin or Madrid adds time, while a northern European hub keeps the detour shorter.

Warsaw has two airports, and which one you land at shapes the rest of your trip. F. Chopin sits inside the city, a short ride from the centre, with a train link and local buses into town and taxis at the curb. Modlin is well outside Warsaw to the north and handles a smaller share of the traffic; from there the journey in is longer and usually done by shuttle bus or car. Check your arrival airport before booking ground transport, since a ticket bought for one will not help at the other. Late arrivals need planning too, as public transport thins out overnight.

Country facts: Wikidata

• Check which Warsaw airport you land at, since F. Chopin and Modlin are far apart.
• Confirm your baggage allowance, especially on a light fare where a checked bag may cost extra.
• If your trip is split across separate tickets, leave a generous gap between flights.
• Make sure your passport is valid for the whole trip and check current entry rules for Poland.
• Compare February with the months around it, since fares shift between winter and summer.
• Weigh the connection airport as well as the fare, because a long layover adds hours.
