Where do I change trains to go to South America?

Go to South America and transfer in the United States, the Middle East or Europe.

If you want to go to Brazil or Argentina, it is recommended to transfer to Dallas. Dallas is the base of American Airlines, and there are flights from Beijing to Guangzhou (basically 787 models), with short transit time and relatively close fares. If you want to go to the Caribbean, it is more convenient to transfer in new york. But there are three major airports in new york, so it is possible to change airports.

If you want to go to some less popular destinations (Ecuador, Peru, Bolivia, Colombia, etc. ), it should be a good choice to transfer in Los Angeles. There are many Latino immigrants in Los Angeles, and all major airlines have opened flights from Los Angeles to South American countries. In addition, the density of domestic flights to Los Angeles is high, and Los Angeles takes into account various convenient conditions.
