Hi! I understand the Air China app is crashing and not opening on your Honor smartphone. Let’s work through that together. To get started, could you tell me if you’ve already tried any steps like restarting your phone or reinstalling the app? Also, which model of Honor phone do you have, if you know? This will help me tailor the solution best for your device.

In the meantime, here’s a straightforward plan we can follow:

1. Restart your phone – Sometimes, a simple reboot clears temporary issues and app cache that might cause crashes.

2. Clear the app cache and data
- Go to your phone’s Settings > Apps or App Management > Find Air China app.
- Tap Storage & cache, then clear cache first. Try opening the app again. If it still crashes, clear data (this resets the app but may require you to log in again).

3. Check for app updates
- Open the Google Play Store (or your app store), go to My apps & games and see if there’s an update available for Air China. Updated versions often fix bugs that cause crashes.

4. Reinstall the app
- Uninstall the Air China app completely, then reinstall it from your app store.

5. Check app permissions
- Still in Settings > Apps > Air China app > Permissions, make sure it has the required permissions enabled (like storage, network).

6. System updates
- Go to Settings > System > Software update to ensure your Android OS is current, as outdated system software can affect app stability.

If you let me know what you’ve tried and your phone model, I can provide more device-specific advice or deeper troubleshooting options from there.

Would you like me to guide you through these steps?
