I flew to the United States for the first time, went to Buffalo, transferred to Tokyo Narita Airport, and then went to new york EWR. What should I do if I check my baggage?

1. Is your ticket through? That is, although ANA changed to United Airlines in Japan, it is actually a tourist itinerary. Even under the flight time of ANA, it is still written that it is operated by United Airlines. Or a confirmation number contains the whole trip. If it is. At Shuangliu Airport, you should hang your checked baggage directly to Buffalo, and put a note to Buffalo on it. Take two or three (Shuangliu-Narita; Narita-NY, new york-Buffalo) boarding pass, and then you don't claim your luggage at Narita Airport, and you don't transfer at UA counter. Just get off the plane, turn around along the connecting sign, pass the security check, and then go to the boarding gate of the next flight.

2. Arrive at EWR. Because it is the first city to arrive in the United States and your port of entry, people have to get off the plane and check their passports, visas and other documents through the immigration office. Next to the immigration office, there is the baggage claim area. Baggage is claimed according to the flight number, and customs clearance is customs clearance. Conduct spot checks. After the customs, it is the airline baggage transfer station, and the baggage is handed over to the staff without any formalities.

Look at the screen to find the connecting terminal and boarding gate, and wait for the plane there. After you went through the customs, you officially entered the United States. You can go anywhere. Whether you go to Manhattan or not depends on whether you have enough time. Note that the plane has to go through security check, and it is best to arrive at the terminal one hour in advance. Be careful, taxi drivers in new york are terrible. They bully foreigners and take detours.

4. Because it is operated by United Airlines, all baggage requirements are in accordance with UA regulations. At present, it seems that a piece of 23kg (50LB) is checked for free. You have to pay more. You can carry a bag (or a female handbag) the size of a computer bag and a bag under 5 kg. (It is recommended to visit UA website)
