1. After arriving at the airport, find the window number for boarding pass according to the flight number of the ticket. Generally speaking, the airport has a big screen to display the counter and flight number.
2. The hauled suitcase should be placed vertically on the conveyor belt, not horizontally. And remember the shape of your suitcase firmly, otherwise you will look at every suitcase when you get off the plane to pick up your luggage, and it will be ugly if you can't find your luggage.
3. Before you pass the security scanning door, you should see if the person in front has finished scanning. If you don't finish scanning, enter the scanning door and the staff will let you out.
After boarding, take-off and landing, the seat back must be put straight, otherwise the stewardess will take care of you.
The above situation is only aimed at large domestic airports. For some small city airports, it is estimated that there are only one or two counters, and there will be no embarrassment.
