Actual fares always depend on your dates, demand and how far ahead you book. - Jan - Feb - Mar - Apr - May - Jun - Jul - Aug - Sep - Oct - Nov - Dec - Lower - Typical - Peak **Usually cheapest:** January and February — Chicago’s coldest weeks — are usually the cheapest time to fly, with four carriers competing for thin off-peak demand. Pack for serious winter weather and the savings can be considerable. **Usually priciest:** Fares peak through the UK summer holidays and over Christmas and New Year; Thanksgiving week also prices firmly on a route heavy with family visits. Summer festivals keep June-to-August demand broad rather than spiky. **When to book:** With around 50 flights a week, this is a comparison shopper’s route — check all four carriers two to four months out and be flexible on departure days.

Four carriers: British Airways, American Airlines, United and Virgin Atlantic — around 50 flights a week combined. All four are rated by FlightLogic, and the two transatlantic joint ventures mean several of those flights are codeshared between partners. ### How long is the flight from Heathrow to Chicago? The westbound leg runs about 8 hours 40 minutes, with the overnight return closer to 7 hours 40 minutes. O’Hare lies roughly 3,945 miles from Heathrow. ### Is O’Hare a good airport for onward connections? Yes — it’s one of the best-positioned hubs in the US, sitting near the country’s geographic centre.
