        "question": "Which cities in United States can I fly from to reach Vietnam?",
        "answer": "From the United States, you can fly non-stop to Vietnam from San Francisco and Los Angeles to Ho Chi Minh City, with seasonal service from San Francisco to Hanoi. For most other US cities, one-stop connections via hubs like Tokyo, Seoul, Hong Kong, or Taipei are common. Travellers often choose departure airports based on proximity, with west coast hubs offering shorter total travel times and often more competitive fares, while those in the central or eastern US may connect through a west coast gateway or Asian hub, weighing layover duration against ticket price."
