        "answer": "From SFO, BART rapid rail is the fastest and most-used way to reach downtown San Francisco, with the station connected directly to the International Terminal via the AirTrain. Ride-share options like Lyft, Uber, and Wingz pick up on Level 5 of the Domestic Garage, while taxis are available at the center islands outside Arrivals. A convenient Rental Car Center is reachable on the AirTrain Blue Line, and SamTrans buses plus Caltrain (via a short BART transfer at Millbrae) offer additional public transit choices. Waymo autonomous rides are also available for select passengers.",

        "question": "When is the cheapest time to fly from São Paulo to San Francisco?",
        "answer": "Average fares from São Paulo to San Francisco bottom out around $427 in late January. The cheapest months overall are September, January, and October, averaging about $436–$443, while the most expensive period is late December at $578. December is the priciest month overall at $548, followed by June and July.",
        "methodology": "Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.",

        "question": "How far in advance should I book tickets from São Paulo to San Francisco?",
        "answer": "For flights from São Paulo to San Francisco, the optimal booking window is about 4 to 6 weeks before departure, with average fares around $419. Booking around 30 days ahead yields the lowest fare (about $417), while booking 175 days or more in advance is the most expensive at roughly $625. For summer and holiday periods, you should book earlier than the 4-6 week window, as prices tend to rise significantly closer to those peak travel dates.",
        "methodology": "Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. It reflects current fares and is refreshed monthly.",

Connecting itineraries whose long overnight leg is a red‑eye are available, with departures typically between 9:30 PM and 11:15 PM from GRU. For example, American Airlines departs at 10:00 PM arriving Dallas‑Fort Worth at 6:15 AM (next morning), United departs at 9:50 PM arriving Houston at 5:45 AM, and LATAM departs at 10:50 PM arriving New York JFK at 7:45 AM — all then connect onward to SFO. Other connecting hubs include Chicago, Washington Dulles, Miami, Los Angeles, and Boston.",
        "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.",

        "answer": "Common layovers include Panama City, Houston, Dallas/Fort Worth, and Miami. Panama City offers efficient Copa Airlines connections with visa‑free transit for many nationalities. Houston and Dallas provide extensive United and American networks with reliable onward flights. Miami serves as a major American Airlines hub with frequent connections to San Francisco."

        "question": "Which airport should I use in San Francisco?",
        "answer": "San Francisco International is the main airport, 13 miles south of downtown. Oakland International and San Jose International are alternatives: Oakland is across the bay and popular with low‑cost carriers, while San Jose serves Silicon Valley."

      "q13": {
        "question": "How do I get to Guarulhos Intl Airport from the city center?",
        "answer": "From central São Paulo, the most popular and comfortable public option is the Airport Bus Service, with lines to key points like Paulista Avenue, Tietê and Barra Funda bus stations, and Congonhas Airport; EMTU also runs a cheaper municipal bus to Tatuapé subway station. Ride-share and taxis are widely available and offer door-to-door convenience, while driving yourself means using private parking at the airport. The Airport Bus Service is generally the fastest public option, while taxis or ride-share are fastest overall but at a higher cost.",

The airport itself is open 24 hours, but there are no designated rest or sleep zones, so travelers often use couches, benches, or recliner-style seating.",

American flies Boeing 787-9s via Dallas and Boeing 777-300ERs via Miami, while Copa uses Boeing 737 MAX 9s via Panama City, Air Canada uses Boeing 787-9s via Toronto, and Delta uses Airbus A330-300s via Atlanta.",
