After the baggage enters the delivery system, the sorting equipment automatically distributes it by scanning the bar code pasted on the baggage and matches it to the designated area according to different flights. Subsequently, for the normal flight of the plane and the safety of passengers, the luggage entering the transportation system has to go through at most five security checks before it can qualify for boarding, including X-ray, CT tomography, trace detection and manual unpacking inspection.
Flight precautions
First find the counter of the corresponding airline (there will be a map at the airport to indicate the corresponding position of each airline), then find the counter of the corresponding seat, and hand over the ID card and air ticket (if booking online, you don't need air ticket, just give the ID card) to the staff for boarding pass. If you arrive early, you can also choose a seat and tell the staff your seat requirements.
The boarding pass has the corresponding security channel written on it. Find the corresponding security channel according to the airport logo. Give the ticket, boarding pass and ID card to the security inspector, and the security inspector will stamp the boarding pass if there is no problem.
Then go through the security gate, take down the metal objects on your body in advance and put them in your carry-on bag. Go through the security gate by yourself, and everything you carry with you must pass through the X-ray security machine next to the security gate. Find your belongings immediately after security check, in case someone steals them.
