        "question": "What is the typical flight duration from Denver to Prague?",
        "answer": "There are no nonstop flights scheduled between Denver and Prague, so the journey requires a connection and typically takes around 11 to 14 hours total depending on the layover. The route distance is about 5,200 miles.",
        "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.",

      "q1": {
        "question": "Are there any direct flights from Denver to Prague?",
        "answer": "There are no nonstop flights from Denver to Prague. The shortest one-stop routings typically connect through Frankfurt or Munich on Lufthansa (or United on the DEN–Germany leg with Lufthansa on the second leg), with total travel time around 11 to 12 hours including a layover of roughly 1 to 3 hours. British Airways via London and Air France via Paris are also options, though those connections tend to be longer.",
        "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.",

        "question": "What are the ground transportation options in Prague?",
        "answer": "From Václav Havel Airport Prague (PRG), the most-used and fastest option to the city center is public transit via trolleybus 59 or bus 100, which connect to the metro in about 20 minutes; a 90-minute ticket costs 40 CZK. Taxis take 25–30 minutes but can be pricey—pre-book or specify the direct route to avoid scams. Ride-share services like Uber and Bolt operate, and car rentals are available but less practical for city-center stays. There is no direct train or metro from the airport. The trolleybus 59 to Metro A is the recommended choice for most travelers.",

        "methodology": "Red-eye flights are identified from scheduled local departure and arrival times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes — flagging services that depart late at night and arrive the following morning; for connecting itineraries the red-eye is based on the timing of the overnight long-haul leg.",

Ride‑share services like Uber and Lyft offer door‑to‑terminal convenience for a higher cost, while taxis provide a fixed‑rate alternative from downtown. Driving and parking on‑site is possible with several lots and a reservation system, though it is generally the most expensive option. Public bus routes also serve the airport but are slower and less direct.",

        "question": "Which airline alliances serve flights from Denver to Prague?",
        "answer": "There is no nonstop service from Denver to Prague, but one-stop itineraries are operated by British Airways (oneworld), Lufthansa and United (both Star Alliance), American Airlines (oneworld), Air France (SkyTeam), and Icelandair (unaffiliated). Star Alliance has the most options via Lufthansa's Munich and Frankfurt hubs and United's codeshares on those same Lufthansa flights, while oneworld appears via British Airways through London and American through Philadelphia; SkyTeam is present through Air France via Paris, and Icelandair offers a non-alliance connection through Reykjavik.",
        "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.",
