Chicago, the great city of the American Midwest, rises along the shores of Lake Michigan with dazzling architecture, deep-dish pizza, blues music and world-famous museums. It is a favourite for UK travellers exploring the US heartland or connecting onwards across North America. The main long-haul gateway is O'Hare International Airport (ORD), with Midway International (MDW) handling domestic routes. Comparing every fare in one place makes finding the right flight from the UK to Chicago quick and simple.
Chicago has four distinct seasons. Late spring (May to June) and early autumn (September to October) bring warm, comfortable days and are ideal for exploring, while summer is lively but busy and winters are famously cold and snowy. Fares typically ease outside the summer and Christmas peaks, so travelling in the shoulder months stretches your budget — check the price charts on this page for your dates.
British Airways, American Airlines and United Airlines fly direct from London Heathrow to Chicago O'Hare in around 8 to 9 hours. Virgin Atlantic also serves the route, and connecting options via other US or European hubs can be better value. Manchester offers seasonal direct or one-stop links. Comparing carriers for your exact dates is the surest way to secure the lowest fare.
Chicago rewards visitors with landmark sights, culture and lakefront charm:
O'Hare sits about 27 km northwest of downtown Chicago, with extensive duty-free shopping, currency exchange, ATMs and dining. The CTA Blue Line train runs directly from the airport into the city centre, alongside taxis, ride-hailing and shuttles. Midway, closer to the south side, is served by the Orange Line.
