        "question": "What is the typical flight duration from Chicago to Vienna?",
        "answer": "The flight from Chicago to Vienna covers about 4,700 miles. Nonstop service on Austrian Airlines takes around 8 hours 45 minutes eastbound, while the return leg is about 10 hours 5 minutes — noticeably longer heading west due to prevailing winds.",
        "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.",

        "question": "Are there any direct flights from Chicago to Vienna?",
        "answer": "Austrian Airlines flies non‑stop from Chicago O'Hare to Vienna, with 11 weekly flights operating daily. Two daily departures are scheduled, one around 4:20 pm and another around 5:20 pm, and the flight takes roughly 8 hours 45 minutes eastbound.",
        "methodology": "Airlines and weekly frequencies are compiled 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 median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours. Carrier service, flight times and distances for this route come from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

You may stay up to 90 days within any 180-day period.\n\nA quick note: this is general guidance to help you plan, not official immigration advice — entry rules can change and can depend on your nationality and circumstances, so please confirm the current requirements with the relevant embassy or official government source before you travel.",

The Vienna S-Bahn line S7 provides local rail service in about 25 minutes, while the more expensive City Airport Train connects directly to Wien Mitte station in 16 minutes. Long-distance Railjet and ICE trains also serve the airport, reaching the main station in roughly 15 minutes. Buses operate to various points in Vienna, and taxis and car rental facilities are available at the airport. The City Airport Train is the fastest option, though the S-Bahn is more commonly used by locals due to its lower cost and integration with the wider transit network.",

Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated.
