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.",

        "question": "What are the ground transportation options in Singapore?",
        "answer": "From Singapore Changi Airport, the Mass Rapid Transit (MRT) train is the most popular and efficient way to reach the city center, taking about 30 minutes with a transfer at Tanah Merah. Taxis are readily available at all terminals, costing S$25–S$45 and offering a direct, comfortable ride. Public buses and a city shuttle bus (S$10 per adult) provide budget-friendly alternatives, while private hire vehicles and car rentals are also options but less commonly used due to Singapore's efficient public transport. The MRT is the most used modality overall, balancing speed, cost, and connectivity.",
