Cheap flights from Warsaw to Denver

January is when fares on this route tend to be at their lowest, and the quieter weeks after the New Year are usually cheap too. Summer is the opposite: school holidays in Poland and the American vacation season push prices up, and December fills fast around Christmas and New Year. Flying midweek, on a Tuesday or Wednesday, usually costs less than a weekend departure, and the first flights of the day are often the cheapest. Book a few months ahead for summer and the winter holidays; for a January trip you can often wait longer and still find a decent fare. Watch out for Thanksgiving in the States if you travel in late November, as it makes connections through American hubs busier.

The airlines that show up on Warsaw to Denver itineraries are network carriers rather than low-cost operators: LOT Polish Airlines, British Airways, Iberia, Finnair, Icelandair, Aer Lingus, TAP Portugal, American Airlines, United Airlines and Nordic Regional Airlines. None of them flies the route non-stop, so every option involves at least one connection, often with a European carrier on the first leg and an American one on the second. What you get included depends on the fare type rather than the brand, so read the baggage and seat rules on the exact ticket you are looking at, and check whether the legs are on one ticket or two.

Denver International is the only airport serving the city, so there is no second option to weigh up on arrival. It sits well outside the city rather than close to downtown, so plan on a transfer of some kind once you land. Public transport, taxis, ride shares and shuttle services all run into the centre, and rental cars are picked up on site if you are heading for the mountains. Allow generous time for the trip back: check-in and security at an airport this size can take a while, and winter weather in Colorado sometimes delays departures.

Country facts: Wikidata

• Warsaw has two airports, F. Chopin and Modlin, so check which one your flight leaves from before booking ground transport.
• Confirm the baggage allowance on the exact fare, because a hand-luggage-only ticket on a long connecting route gets expensive.
• Make sure both legs are on one ticket, or a missed connection becomes your problem rather than the airline's.
• Check your passport and the US entry requirements well ahead, including any electronic travel authorisation.
• If January's low fares are the reason for the trip, build in slack for snow delays at either end.
