Cheap flights from Warsaw to Ontario

Warsaw to Ontario is a long-haul trip that always involves at least one change, as no airline flies the route nonstop.

When to fly

April is the cheapest month on this route, and the months on either side often come close, so compare spring and autumn departures instead of taking the first fare you see. Summer is peak family-travel season, and late November through early January fills planes with Thanksgiving and Christmas traffic — book those trips well ahead. Midweek departures, Tuesday to Thursday, usually cost less than a weekend flight, and Polish holiday periods fill and empty Warsaw's airports in their own rhythm. If your dates are flexible, the price calendar is the quickest way to see which month suits your budget.

Airlines and what to expect

No carrier flies Warsaw to Ontario nonstop, so every option is a connecting itinerary. The names you will see are mostly full-service: LOT Polish Airlines, Lufthansa and its Cityline regional arm, Swiss, Austrian, British Airways and Air Baltic on the European side, plus American Airlines, United Airlines and Delta Air Lines on the American side. What separates them is where you change planes, how long the layover is and how the ticket is put together — a single through-ticket protects you if a leg is delayed, while separate tickets do not. Baggage rules follow the fare you buy rather than the airline name, so read them before you pay.

Arriving — Ontario

You land at LA/Ontario International, the airport that carries this route on the American side. The name can trip people up, so check that your ticket and your pickup both say Ontario and not another Los Angeles-area airport. The terminal sits a short ride from the centre of Ontario, and most travellers get into town by taxi, rideshare, rental car or a hotel shuttle; local buses run as well but take longer. Freeway traffic is the thing to plan around, particularly in the late afternoon, so leave more time than the distance suggests if you are travelling on.

Check before you book

  • Confirm whether you leave from F. Chopin or Modlin, since Warsaw uses two airports.
  • Check the baggage allowance for the whole itinerary, not just the first leg.
  • If your legs are on separate tickets, leave a generous buffer for the connection.
  • Make sure your passport and any US entry authorisation cover the full trip.
  • Compare April fares against the months on either side before you commit.
  • Look at where you change planes and how long the layover really is.
