        "question": "Are there visa requirements to travel from Charlotte to San Juan?",
        "answer": "Puerto Rico is a U.S. territory, so travel between Charlotte and San Juan is domestic for U.S. citizens and permanent residents and requires no visa or passport.

      },
      "q3": {
        "question": "What are the ground transportation options in San Juan?",
        "answer": "Luis Munoz Marin International Airport sits about seven miles east of downtown San Juan. Taxis are the most commonly used option, with fixed fares to major zones including Old San Juan and the Condado hotel district, making pricing predictable. Ride-share services such as Uber operate in San Juan and are generally affordable and convenient. The Tren Urbano metro system does not directly serve the airport, limiting mass transit options for arriving passengers. Public buses run nearby but are slow and infrequent, making them impractical for most travelers with luggage. Car rentals are widely available at the airport and are popular given that Puerto Rico has extensive road infrastructure and many attractions beyond the city. For most visitors staying in the tourist areas of Condado or Old San Juan, taxis or ride-share services offer the best balance of cost and convenience."

For summer travel or holiday periods like Thanksgiving, Christmas, or spring break, it's wise to book even earlier — ideally 3–4 months out — since demand for Puerto Rico surges and the best fares get snapped up faster.",
