Can I upgrade after security check?
This situation can be escalated.
China International Airlines official website shows that the way to upgrade from economy class to business class at the boarding gate can be handled through "China International Airlines" WeChat applet or "Air China APP". You can also pay attention to the SMS notification after check-in, and click the link in the SMS for processing. The processing time is to upgrade the cabin after passing the security check, and processing in advance may affect the security check.
The processing time for domestic routes is 90 minutes to 55 minutes before departure, and the processing time for international/regional routes is 90 minutes to 65 minutes before departure.
