        "answer": "From Porto Airport (OPO), you can reach the city center by metro, bus, taxi, ride-share, or rental car. The metro's Line E (Violet Line) is the fastest and most-used option, taking about 25–30 minutes to central Porto. Buses like STCP lines 601 and 602 are cheaper but slower. Taxis and ride-shares are available at the curb, offering door-to-door convenience at a higher cost. Car rentals are also on-site if you plan to explore beyond the city.",

        "answer": "No nonstop red‑eye flights operate from Houston (HOU) to Porto (OPO), but connecting itineraries whose long leg is an overnight red‑eye are available. One option connects via Frankfurt: United departs Houston (IAH) at 6:20 PM and arrives Frankfurt at 11:15 AM the next morning, then connects to Lufthansa with a layover of about 2h35m. Other connections route through Newark or Boston on United or TAP Air Portugal with late‑evening transatlantic departures and next‑morning arrivals in Porto.",
        "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.",

KLM via Amsterdam, Air Canada via Montréal, Air France via Paris, and TAP Air Portugal via Newark or Boston each offer about two connections per day.",
        "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.",

        "answer": "Common layovers for Houston to Porto include Lisbon, Madrid, Amsterdam and Paris. Lisbon is the primary gateway into Portugal with frequent connections to Porto. Madrid offers broad connections and efficient transfers within the Schengen area. Amsterdam and Paris are major European hubs with extensive networks and smooth transit processes, often keeping total travel time competitive."

        "question": "Which airport should I use in Porto?",
        "answer": "Porto has only one airport, Francisco Sá Carneiro Airport, located about 11 km northwest of the city centre. It serves both full‑service and low‑cost carriers and is the sole gateway to the region."
      },
      "q13": {
        "question": "How do I get to William P Hobby Airport from the city center?",
        "answer": "From downtown Houston, you can take a taxi or ride-share directly to Hobby Airport in about 20 minutes, which is the most popular and convenient option. Public transit is available via METRO Bus 40, which connects to the airport with a longer travel time and lower cost. Driving and parking are also possible, with on-site garage and lot options, though advance booking can save significantly on parking fees.",
