        "question": "What is the typical flight duration from Seoul to Tokyo?",
        "answer": "A nonstop flight from Seoul (ICN) to Tokyo (NRT/HND) typically takes about 2 hours 20 minutes to 2 hours 40 minutes. The return flight is usually slightly shorter, around 2 hours to 2 hours 20 minutes, due to prevailing tailwinds. With a layover, total travel time often exceeds 5 hours."
      },
      "q1": {
        "question": "Are there any direct flights from Seoul to Tokyo?",
        "answer": "Yes, there are abundant non‑stop flights from Seoul Incheon (ICN) to Tokyo (TYO), with 15 carriers serving the route across both Narita (NRT) and Haneda (HND). Most airlines fly daily, including Korean Air (8 daily departures to NRT, 2 to HND), Asiana (5 to NRT, 2 to HND), Jin Air (5 to NRT), Jeju Air (4 to NRT), T'way Air (3 to NRT), Eastar Jet (3 to NRT), Air Seoul (3 to NRT), Air Busan (2 to NRT), and Peach Aviation (1 to HND), among others. A couple of carriers are not quite daily: Air Premia and Ethiopian Airlines each operate six days a week to NRT (no Tuesday or Wednesday, respectively).",
        "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.",

        "question": "Are there visa requirements to travel from Seoul to Tokyo?",
        "answer": "Yes, there are visa requirements for travel from Seoul to Tokyo. South Korean nationals can enter Japan visa-free for short stays (typically up to 90 days) for tourism or business. Japanese nationals do not need a visa to enter South Korea for short stays (up to 90 days). Third-country nationals should check their specific visa requirements for both Japan and South Korea, as rules vary by nationality."

        "question": "What are the ground transportation options in Tokyo?",
        "answer": "At Tokyo Narita, the fastest and most popular way to central Tokyo is the Narita Express (N'EX) train, reaching Tokyo Station in 55–60 minutes for ¥2,870 one-way; the Keisei Skyliner offers a competing rail option. Buses serve many city hotels and are cheaper but slower, while taxis are available but very expensive (often over ¥20,000). Ride-share services are not widely available in Japan, and rental cars are an option but not recommended for city-center travel due to congestion and parking costs.",

        "question": "How do I get to Incheon Intl Airport from the city center?",
        "answer": "From downtown Seoul, the fastest and most popular way to reach Incheon Airport is the AREX express train, which takes about 43 minutes non-stop to Terminal 1 and 2. More affordable AREX all-stop commuter trains also run frequently, taking around 60 minutes. Airport limousine buses serve major districts and hotels, taking 60–90 minutes depending on traffic, with fares around 17,000–18,000 won for an adult. Taxis and ride‑share offer door‑to‑door convenience but are the most expensive option, while driving yourself is possible with both short‑term and long‑term parking available at the airport.",
