There are three common ways to check in:
1. Counter check-in means going to the airport counter to select seats, confirm information and print boarding passes. If you have any luggage to check, please check it at the counter.
2. The online check-in procedure is to go to the airline official website to choose a seat. If you support printing boarding passes on A4 paper, you can print boarding passes directly on A4 paper. But if you need to check your luggage, you still need to check it at the counter.
3. The APP check-in process is to download the Empty Track Butler APP, click the check-in to select a seat, and select a seat. There are boarding passes that can be printed for free at the airport. If checked, the airport staff will send you the printed boarding pass. If you need to check your luggage, the staff will take it to the baggage check-in office.
Extended data:
Check in at the check-in counter in the terminal.
After arriving at the airport, go directly to the check-in counter of the airline to which the ticket belongs. If there is a big screen of the ticket information system in the departure hall, you can look up your flight number and go to the corresponding counter to go through the formalities. If you take the previous promissory note, you can go through the check-in formalities except the promissory note with your ID card. If you buy an electronic ticket, you can go directly to the check-in counter with your ID card.
Then the check-in staff will give you a boarding pass with your seat number and boarding gate on it, so follow the airport sign to the nearest security area for security check.
Finally, after the security check, check the boarding gate of your boarding pass according to the signs in the waiting hall. Just sit and wait when you find it. While waiting, pay attention to the airport broadcast or the instructions of the staff at this boarding gate, because they will tell you when you can start boarding.
