        "question": "What is the typical flight duration from Istanbul to Chicago?",
        "answer": "The flight from Istanbul to Chicago covers about 5,460 miles. Nonstop service on Turkish Airlines takes 11 hours 30 minutes outbound, while the return leg is about 10 hours 30 minutes — a full hour shorter heading east with the jet stream.",
        "methodology": "Flight times and distances 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). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

        "answer": "At Chicago O'Hare, you can reach the city center via the CTA Blue Line 'L' train, which is the most-used and economical option with a station right in the airport. Taxis, limos, and rideshare services like Uber and Lyft provide direct door-to-door convenience, while rental cars and regional buses are also available. The Blue Line is typically the fastest during peak traffic, though rideshares or taxis can be quicker off-peak.",

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.

      "q12": {
        "question": "Which airport should I use in Chicago?",
        "answer": "Chicago has two main airports. O'Hare is the major international hub, located about 17 miles northwest of downtown, serving as a base for United and American Airlines with extensive global connections. Midway is about 10 miles southwest of downtown, primarily serving Southwest Airlines with domestic and some near-international flights, and is often preferred for its proximity and ease of access to the city center."
      },
      "q13": {
        "question": "How do I get to İstanbul Airport from the city center?",
        "answer": "From Istanbul's city center to Istanbul Airport (IST), you can take the Havaist airport shuttle buses, public buses, taxis, ride‑share services, or drive and park in one of the airport's car parks. The Havaist shuttles are the most popular option, offering a reliable and comfortable ride with fixed routes from key points like Taksim and Sultanahmet at a moderate cost. Taxis and ride‑shares provide door‑to‑door convenience and are faster, especially outside peak traffic, but are the most expensive. Public buses are the cheapest, though they can be slow and crowded, while driving and parking is an option with several lots available, but city traffic can be unpredictable.",
