        "question": "What is the typical flight duration from Delhi to Singapore?",
        "answer": "A nonstop flight from Delhi (DEL) to Singapore (SIN) typically takes about 5 hours and 45 minutes to 6 hours. The return flight from Singapore to Delhi is slightly longer, usually around 6 hours and 10 minutes. Flights with a layover, most commonly in Kuala Lumpur or Bangkok, can extend total travel time to 8 to 10 hours or more depending on the connection duration."

      "q1": {
        "question": "Are there any direct flights from Delhi to Singapore?",
        "answer": "Yes, there are direct non‑stop flights from Delhi to Singapore. Three airlines operate the route daily: Singapore Airlines (4 flights a day), Air India (3 flights a day), and IndiGo (2 flights a day), for a total of 63 weekly non‑stops.",
        "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 and weekly frequencies are summarized 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). Where available, on-time and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, and typical fares from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

In the reverse direction, Singaporean citizens enjoy visa-free access to India for tourism and certain other short visits, typically up to 90 days. Travelers of other nationalities should check Singapore's visa requirements based on their passport, as many countries have visa-free arrangements for short stays."

      "q3": {
        "question": "What are the ground transportation options in Singapore?",
        "answer": "From Singapore Changi Airport, the MRT train is the most popular and efficient way to reach the city center, with a transfer at Tanah Merah station and a journey time of around 30 minutes. Taxis are also readily available, costing between S$25 and S$45 for a 30-minute ride, while the City Shuttle bus serves many hotels at S$10 per adult. Public buses are an option, but require exact fare if paying by cash. Ride-share services like Grab operate widely, and car rentals are available though less commonly used due to Singapore's excellent public transit. The MRT is the most used option overall, praised for its reliability and affordability.",
