The overnight leg from Chicago O'Hare typically departs between 4:05 PM and 7:05 PM and arrives at the European hub between 6:50 AM and 10:50 AM the next morning. Carriers include Lufthansa (via Frankfurt, arriving 7:25 AM), KLM (via Amsterdam, arriving 7:35 AM), Iberia (via Madrid, arriving 8:20 AM), Swiss (via Zurich, arriving 10:50 AM), Air France (via Paris CDG, arriving 8:15 AM), Air Serbia (via Belgrade, arriving 9:20 AM), British Airways (via London Heathrow, arriving 6:50 AM), and United (via Frankfurt, arriving 9:55 AM); one itinerary also connects through Philadelphia on American, arriving Budapest at 8:10 AM.",

Lufthansa via Frankfurt or Munich offers the most frequent connections, with up to 9 daily flights via Frankfurt and 7 via Munich. Finnair, SWISS, KLM, Turkish Airlines, Iberia, and Air France also operate regular one-stop routings, typically with 2–4 daily frequencies each. Other carriers like United (via Frankfurt or Zurich), LOT Polish, British Airways, Aer Lingus, and American (via Philadelphia) appear with lower daily frequency. No per-carrier fares are available for this route.",
        "methodology": "Airlines and weekly frequencies come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a typical fare is shown for a carrier, it is the median of the real fares Priceline users found on this route in the last 72 hours.",

        "answer": "DuPage Airport (DPA) in West Chicago is a general aviation reliever airport about 30 miles west of downtown Chicago, with no direct public transit link from the city center. The most practical options are driving (about 45–60 minutes via I-290/I-88), using a ride-share or taxi (typically $60–90 one way), or taking a Metra commuter train to a nearby suburb like West Chicago or Wheaton and then a short taxi or ride-share to the airport. Pace suburban buses serve the DuPage County area but do not run directly from downtown Chicago to DPA, so a multi-leg trip is required. Driving and ride-share are the most popular choices, with driving offering the most flexibility and ride-share being the easiest door-to-door option.",
