Cheap flights from Chicago to Warsaw

January is the cheapest month to fly this route, so if your dates are flexible, aim for the start of the year. Summer and the run-up to Christmas are the busiest stretches, when seats fill up and fares climb. Flying midweek rather than at the weekend usually gives you more choice. In Chicago, Thanksgiving and the winter holidays push up demand, while in Warsaw the Christmas and Easter periods do the same. Booking a few months ahead helps, especially for summer travel. The price calendar on this page shows what each month looks like.

No airline flies this route non-stop, so every option is a connecting itinerary. The carriers you'll see include Air Canada, Scandinavian Airlines, British Airways, Iberia, AeroMéxico, American Airlines, Envoy Air, Turkish Airlines, TAP Portugal and Aer Lingus. Most are full-service airlines, which means a checked bag and meals are often part of the fare, but the details depend on the ticket you buy. Envoy Air is a regional partner, so it may operate a shorter leg on behalf of a bigger carrier. Low-cost carriers aren't a big feature here, so compare what each fare actually includes before you choose.

Warsaw has two airports: F. Chopin, which is the closer one to the centre, and Modlin, which sits further out to the north. From Chopin you can reach the middle of town by train, bus or taxi, and the journey is short. Modlin is served by shuttle buses and train links that take longer. Check your ticket carefully, because the two airports are far apart and a mix-up can cost you time. Also allow plenty of room for your connection if you are arriving on a separate ticket.

• Decide whether you want to leave from Midway International or O'Hare International, and check which one your fare uses.
• Look at what baggage is included, because a cheaper fare may not cover a checked bag.
• If you book the two legs on separate tickets, leave a generous buffer between flights in case the first one is delayed.
• Check your passport and any entry requirements for Poland well before you travel.
• Use the price calendar to compare months, and keep in mind that January is the cheapest.
