What's the difference between checking in and not checking in?

You can't get into the security checkpoint without a machine. Checking in means that you are sure to fly that day and choose a good seat.

Simply put, after entering the airport, use your ID card to print out the flight on the boarding pass printer, including the selected seats. You can also queue up at the window to check in and check in your luggage at the same time. You can also use your mobile phone to check in online and get a boarding pass with an electronic QR code.

Passenger planes have strict control over the number of passengers, and check-in can further clarify the number of passengers. At the same time, it is necessary to check in when traveling by air, so that passengers can control it. Unlike trains and cars, airplanes have very high requirements for load configuration. One more boarding is to ensure the balance of the plane.

In order to keep the balance of the flight, the stowage department will calculate the balance parameters of the aircraft according to the passenger capacity and cargo weight after the aircraft model and passenger capacity are basically determined, and then allocate the seat numbers reasonably before starting the check-in to select seats.

However, after the pre-selection of seats, passengers may be reassigned to other seats by airlines due to loading reasons. There are also cases of temporary replacement of models. Even for two planes of the same model, the cockpit layout may be slightly different, which needs to be checked in for further confirmation.

The origin of sign-in

With the development of economy, more and more people choose airplanes as travel tools, because the biggest advantage of air travel lies in its rapidity. However, due to the relatively complex flight process, each link consumes a lot of passengers' time, which makes passengers spend a very long time on the ground and weakens the advantages of air travel to a certain extent.

The check-in link in the flight process is mainly for passengers to change their air tickets into boarding passes and check their luggage. Congestion often occurs during busy hours. There are many reasons for congestion. For example, many airports do not use fully open check-in, which makes some check-in machines have a large number of people waiting in line, but some check-in machines are idle, so the check-in machines are not fully utilized.

In addition, due to the check-in of luggage, the luggage condition of each passenger is different. If the luggage of the previous passenger is slow and piled up like a mountain, it will make the passengers behind spend a lot of time waiting in line.

In addition, there are some procedures arranged in sequence, which will also cause passengers to queue up. Because airport construction generally has a certain sense of advance, it is necessary to consider that the airport can handle the corresponding throughput after the passenger volume increases to a certain number in the next few years.

However, the passengers are far from the forecast, and the airport check-in machine is partially saturated, which shows that there are some problems in the existing processes, and these processes need to be optimized to make full and reasonable use of airport facilities.
