Thanks to @AmericanAirlines, American Airlines invited to Rio to participate in the Carnival. From Hong Kong, take the American Airlines business class to Brazil. Long-distance flights can be found all the way to reduce the fatigue of the journey. Just know that American Airlines is the world's largest airline. ) Boeing 777-300er model business class in a row of four, are corridors, the surprise is that the aircraft uses the global sleep technology company Casper products, all the way to sleep is very comfortable. The meal on the meal is also worth recommending. The first time I eat the vegetable salad on the plane, I want a second copy. The Chinese meal is also very good! Wi-Fi service is available throughout the plane and can be used in the air. Other hardware is also good, Bose noise canceling headphones, COLE HAAN American brand wash bag, entertainment system with more than 200 movies. From the departure of China, there are flight attendants on the plane who speak Chinese, which is convenient for passengers who do not speak the language. 14 hours from China to the United States, 10 hours from the United States to Brazil, luggage is still very convenient, recommended to small partners planning to travel to South America.
