        "question": "What is the typical flight duration from Delhi to Singapore?",
        "answer": "The nonstop flight from Delhi to Singapore covers about 2,590 miles and typically takes 5 hours 55 minutes. The return leg is about 5 hours 50 minutes, making the outbound direction slightly longer. Connecting itineraries generally add two to four hours to the total journey time.",
        "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 Delhi to Singapore?",
        "answer": "Yes, there are direct flights from Delhi to Singapore on three airlines: Singapore Airlines (SQ), Air India (AI), and IndiGo (6E), all operating daily. Singapore Airlines offers up to 28 weekly non‑stops, Air India 21, and IndiGo 14, with departures spread across the morning and late evening. The flight takes about 5 hours 55 minutes eastbound and roughly 5 hours 50 minutes on the return.",
        "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 Singapore?",
        "answer": "From Singapore Changi Airport (SIN), the MRT (Mass Rapid Transit) train is the most affordable and commonly used way into the city, with Changi Airport MRT Station directly serving Terminals 2 and 3, and a transfer at Tanah Merah or Expo to continue to the city center. Taxis are readily available at all terminals, with metered fares and surcharges, taking about 20–30 minutes to the city; ride-hailing apps like Grab, Gojek, Zig, and Tada also operate with designated pick-up points. Public buses (routes 24, 27, 34, 36, 44, 53, 110, and 858) serve Terminals 1–3, and car rental or private transfers are available for point-to-point travel, though private car ownership is heavily restricted and expensive in Singapore. The MRT is the most-used option for airport-to-city travel due to its low cost, reliability, and direct terminal connections.",

        "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.",

        "question": "How do I get to Indira Gandhi Intl Airport from the city center?",
        "answer": "The Delhi Metro's Airport Express Line is the fastest public transport link to Indira Gandhi International Airport, connecting New Delhi Railway Station to the terminals in about 20 minutes and avoiding road traffic. Delhi Transport Corporation (DTC) buses, including air-conditioned and low-floor services, are the most popular and economical option, with extensive routes from across the city. Ride-share apps like Uber and Ola, along with radio taxis and auto-rickshaws, offer convenient door-to-door travel at a higher cost. Driving is possible via the Delhi-Gurgaon Expressway and the airport has parking, but congestion can make this the slowest choice during peak hours.",

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.

        "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.",
