1, from Shanghai to new york
Both China Eastern Airlines and United Airlines have direct flights, with two round trips for China Eastern Airlines and 1 round trip for United Airlines every day.
If the price difference is not big, and you want to make the best use of it, you can choose China Eastern Airlines 1 1:30 to set sail and come back and choose 16:25 to make the best use of your travel time. It should be reminded that the airport where China Eastern Airlines landed was Kennedy Airport, and the airport where United Airlines landed was Newark Airport.
Kennedy Airport is about 1 hour drive from Manhattan, but China Eastern Airlines operates twice a day, and its departure time is diversified. Newark Airport is only half an hour away from Manhattan, just across the bridge. It is the seat of United Airlines, and there are many flights to other American cities.
As for the price, there is little difference between economy class fare and one-way and round-trip fare. Business class, it seems that the price advantage of China Eastern Airlines is obvious at present.
Of course, if the price is the same, then China Eastern Airlines is also recommended. Because the pattern, meals and services of business class and first class on the new model have been greatly improved.
2. Shanghai to San Francisco
China Eastern Airlines and United Airlines have direct flights, United Airlines has two round trips, and China Eastern Airlines has daily flights 1. ?
Because there are two flights, United Airlines has an advantage on the San Francisco route. The price of economy class is not much different, and the round-trip business class of United Airlines is the cheapest. If it is a one-way trip, China Eastern Airlines is the cheapest. Similarly, if the price is the same, I recommend the business class of China Eastern Airlines.
