The mini app can also track checked luggage, so you can finally know where your luggage is.

Every time I take a plane and wait for my luggage to be checked in, I always wonder if my luggage has been lost or transported to a black hole. Otherwise, why hasn’t my luggage arrived after so long?

If you knew where your luggage was, you might not be so anxious waiting for it.

Starting from September 10, passengers on the Shenzhen-Shanghai Hongqiao flights operated by China Eastern Airlines and Shanghai Airlines can check the transportation status of their checked baggage in real time after completing the baggage check-in procedures. After the service is launched, it is expected that more than 2,000 passengers will try it out every day.

Both the "Shenzhen Airport" and "China Eastern Airlines" WeChat mini-programs can support real-time query of the transportation status of checked baggage. Shenzhen Airport said that it will work with other airlines to gradually launch more routes that support RFID baggage location tracking and continuously expand the service coverage.

RFID is radio frequency identification technology, which is considered to be one of the most promising information technologies in the 21st century. It uses wireless radio frequency to carry out non-contact two-way data communication and uses wireless radio frequency to read and write recording media (electronic tags or radio frequency cards), thereby achieving the purpose of identifying targets and exchanging data.

The electronic luggage tags previously launched by China Eastern Airlines and China Southern Airlines also use built-in RFID identification chips to track location, so passengers can update their luggage check-in information in real time after changing flights.

Compared with an electronic boarding pass that costs 688 yuan, using a mini program to confirm the location of luggage is less expensive.

However, the RFID identification chip is essential for the baggage tracking process. Before using the mini program to track your baggage, the airport ground service staff will attach an RFID baggage tag to your baggage. In this way, the subsequent baggage consignment, sorting, loading, loading and arrival can be sensed and matched in real time, so that people and bags can be quickly matched, information can be transmitted in seconds, and the whole process of baggage positioning and tracking can be realized.

Baggage check-in and baggage collection are only part of the flight process. The rest include offline steps such as ticketing and security checks. Recently, we have also found that the role of mini programs in aviation services is gradually becoming more prominent.

The "Civil Aviation Temporary Boarding Certificate" mini program launched on the same day can help users who forget to bring or lose their ID cards to conduct "real-person identity verification" and efficiently issue temporary boarding certificates, further promoting the process of "paperless" and convenient travel for civil aviation passengers.

Frequent flyers may have four or five airline apps installed on their phones, but for those who only fly once every three or four months, installing so many apps is a waste of resources. Mini programs are a better choice for these low- and medium-frequency users.

China Southern Airlines regards mini programs as a means to improve passengers' offline service experience:

• Improve the service experience in offline scenarios and combine scenario-based service functions to enable passengers to quickly handle the required services by themselves.

As one of the first developers of WeChat Mini Programs, Spring Airlines was the first to provide users with a convenient service to check flight status. In addition, they will also use the Mini Program to carry some new and experimental services.

For example, the "WeChat In-flight Payment" jointly created with WeChat Pay uses the mini program as a carrier. Users with a WeChat payment score of 550 or above can enter the "Spring Airlines" mini program before boarding the plane and experience the experience of paying first and then enjoying the flight at an altitude of 10,000 meters.

For such airlines, mini programs with low user barriers are a testing ground for trying new services.

Tracking your luggage, issuing temporary boarding certificates, allowing you to enjoy services even in flight mode... What other mini-app features of airlines do you think are good or innovative?
