San Francisco airport in the United States is in a hurry! !

Both UA858 and UA862 are at San Francisco International Airport (airport code: SFO).

Let's talk about the entry and transfer process of San Francisco International Airport in detail, so as to give you a general impression that the transfer may be more convenient:

1) On the UA858 flight from China Pudong Airport (airport code PVG) to San Francisco International Airport (airport code SFO), fill in the I-94 form and customs declaration form (which will be sent to passengers by flight attendants). Fill in these two forms in English.

2) Upon arrival at San Francisco International Airport (airport code: SFO), all inbound international flights stop at the international terminal. Get off the plane and follow the people. There is only one way to the Immigration Hall. There are two different queues [one is American citizens and green card holders, and the other is non-immigrant visitors]. See the immigration officer, hand over your I-94, show your passport and customs declaration form, and other materials [generally study abroad-the official will ask you to show me I-20, etc. The official of the US Immigration Bureau approved that the half chapter of I-94 (exit card) should be affixed to your passport (this half chapter of I-94 is very important, don't lose it, and hand it in when you leave the United States). This program takes a long time because there are many people waiting in line. Generally, it takes about 1 hour. Sometimes, there are not many passengers, and half an hour is possible; Sometimes it takes more than an hour for several international flights to arrive at the same time.

3) Pick up your checked baggage on the baggage carousel of your flight.

4) After the customs inspection, they submit the customs report and conduct spot checks. There are three situations: one possibility is that the customs officer receives your customs declaration form, then waves his hand and you leave; On the other hand, they accept your customs declaration form and ask you to put your luggage (all luggage, including checked luggage and carry-on luggage) on the conveyor belt of the inspection machine. After the luggage comes, no one is looking for you, so just put it on the trolley and go. There is a third possibility. After the machine inspection, some customs officers ask for unpacking inspection. You have to take all your luggage to the customs inspection counter and open it on the spot for them to check. As long as it is not the third case, generally speaking, 10 for several minutes. If it is unpacking inspection, it is difficult to estimate the time. Generally speaking, most of them are the second case.

5) You bought a joint flight ticket (airport code BOS) from Shanghai Pudong Airport to Boston, so you should give it directly to the baggage handler (be careful not to damage or lose the airline baggage tag on your checked baggage, which has the names of the departure airport and destination airport of your baggage). Look for your airline, the conveyor belt of United Airlines (UA) [just at the exit of the customs inspection office, there is a sign next to their airline staff] and post it.

6) Find your boarding gate at San Francisco International Airport. You have to get off at the "International Building" of San Francisco Airport, while domestic flights to other parts of the United States are in another terminal. San Francisco airport is relatively large. The departure flight of United Airlines is usually in Terminal 3.

You bought a joint flight ticket from United Airlines Beijing Capital Airport to your destination. Generally speaking, when boarding at China Pudong Airport, UA check-in counter will give you the boarding pass from Shanghai Pudong Airport (airport code PVG) to San Francisco (airport code SFO) and the boarding pass for connecting flight in San Francisco. The boarding pass has the flight number (UA862) from San Francisco to the airport you want to go to, and sometimes there is the terminal for boarding at San Francisco International Airport. If you don't have the terminal and boarding gate numbers, just look at the flight indication TV screen of San Francisco Airport and compare your flight number to see the corresponding boarding gate. If you don't get your boarding pass at the last stop of Shanghai Pudong Airport, you should take the initiative to ask the staff at UA check-in counter. By the way, the flight status display form in the United States is a little different from that in China. China is in chronological order, and the United States is generally arranged alphabetically. ]

Please check the security again before entering this terminal. The length of the security queue depends on whether your time is at the peak.

The sign of San Francisco airport is very clear. You know English, so you can understand.

In short, the whole process of customs clearance and transit in San Francisco takes about 1 hour.

In addition: Pay attention to the airport sign after leaving the "International Building" in San Francisco, and head for Terminal 3. Because, if you are not careful, you will turn back to the international building.
