Cheap flights from Warsaw to Chicago

December is when fares on this route tend to be at their lowest, though the weeks around Christmas and New Year fill up fast and get expensive, so book early if you want to travel then. Late autumn and the first half of winter are generally quiet apart from the holiday peak. Summer is the busiest stretch, when Polish families fly out and Americans come the other way, and July and August prices reflect that. Midweek departures, especially Tuesday and Wednesday, are usually cheaper than Friday and Sunday. Book a few months ahead for summer and holiday travel; for the quiet months you can often wait and watch the price calendar.

The carriers that show up on Warsaw to Chicago itineraries are Scandinavian Airlines, Cityjet, Aer Lingus, British Airways, Iberia, American Airlines, LOT Polish Airlines, Finnair, TAP Portugal and Icelandair. Because the route is not flown non-stop, every one of them sells a connection through a hub, and the airline you book with may not be the one flying every leg. What is included varies by carrier and fare: a checked bag, seat selection and meals are standard on some tickets and add-ons on others, and short connecting legs can have tighter cabin baggage limits.

Chicago has two airports, and which one you land at shapes the last part of the trip. O'Hare International lies northwest of the city and handles most of the long-haul traffic; the rail line from there runs into the centre and takes a while but avoids the traffic. Midway International is closer in on the southwest side, smaller and quicker to get through, with its own rail link and a short ride to the downtown hotels. Immigration queues can be long at either airport, so leave room in your plans, and if you are connecting onward, check that your arrival and departure airports match.

Country facts: Wikidata

• Check whether you leave from F. Chopin or Modlin, since these are two separate airports.
• Confirm what your fare includes for checked bags, as lighter fares charge per bag on each leg.
• If your connection is on separate tickets, leave a generous gap so a delay does not cost you the onward flight.
• Make sure your passport and any US visa or travel authorisation are valid before you pay.
• Decide between O'Hare and Midway first, as they put you in different parts of the city.
• Watch the price calendar across the year, with December usually the cheapest month and summer the priciest.
