The difference between mobile phone check-in and on-site check-in

1. Self-help check-in machine is a brand-new check-in method, which is different from the traditional airport counter check-in. Passengers using self-service check-in machines don't have to wait in line at the airport check-in counter for the service staff to print the boarding pass invoice and allocate seats for you. Instead, passengers can obtain all flight information from self-service check-in equipment through specific check-in vouchers, select seats and confirm information according to the screen prompts, and finally get boarding passes and invoices. The whole process is completely operated by passengers themselves, which is a brand-new DIY check-in method. It can be obtained by telephone, website, mobile phone and airport self-service check-in equipment.

2. Online check-in service-referred to as "online check-in" service, is a convenient and fast check-in method. If you don't need to check your luggage, you can book your seat in advance through online check-in, print out your boarding pass, and board the plane directly through security check, so you don't have to queue up at the airport service counter to get your boarding pass, which can save time. Online check-in is an online service that is convenient for travel. Today, major airlines have launched this service in their respective official website. Some companies such as China Southern Airlines in Guangzhou and China Eastern Airlines in Shanghai Airport also support QR code check-in.

3. Manual check-in, that is, counter check-in. Passengers' boarding pass exchange and baggage registration are integrated at the same time and place at the airport, led by airport or airline service personnel.

4. Mobile phone check-in: refers to passengers using mobile phones to log in to the self-service check-in interface of the airline departure system, and complete the verification of identity documents and the selection and determination of seats by themselves. Airlines send electronic boarding passes with two-dimensional bar codes to passengers' mobile phones in the form of short messages. When passengers arrive at the airport, they complete baggage check-in, print boarding passes or directly scan QR codes to complete security inspection.

5. SMS check-in: It means that passengers go through check-in procedures by sending and receiving SMS. The first phase of SMS check-in service is only applicable to single adult passengers who handle non-transit and non-code domestic flights of China Southern Airlines.
