How to Fix Frontier Airlines App Not Working

There are a number of proven tech tips that can prevent the Frontier Airlines app from stopping, freezing, and crashing.

1. Check if Frontier Airlines app’s down. The Frontier Airlines service could be experiencing a server outage or other technical issues.

2. Check your phone’s Wi-Fi or cellular connection. The quickest way to do this is to open another app that needs an internet connection. If Wi-Fi is slow or down, switch to cellular. If cellular is slow or down, switch to Wi-Fi.

The process of switching between Wi-Fi and Cellular connection depends on your platform: Android, or iPhone.

3. Toggle Airplane Mode on and off. This only takes a few seconds and is an easy way to reset your phone’s Wi-Fi and cellular connections. (AndroidiPhone)

4. Restart the Frontier Airlines app. Properly closing the Frontier Airlines app, not just minimizing it, and then opening it again could fix the problem. (AndroidiPhone)

5. Restart your device. Restarting your mobile device will often clear most problems. So take a moment to reboot your Android or reboot your iOS device to see if it resolves problems with Frontier Airlines app not working.

6. Check for Frontier Airlines app updates. Check for and install any Frontier Airlines app updates on your Android device or app updates on your iPhone. If your Frontier Airlines app is ever out of date, it can lead to connection errors and other issues that may lead to Frontier Airlines not working on your mobile device.

7. Clear the Frontier Airlines app cache on your Android device or clear the cache on an iPhone. While caching improves app performance by saving app information in local memory, it can also lead to issues with your device not receiving the latest information from Frontier Airlines. Clearing cached data will force your app to retrieve the latest information from Frontier Airlines.

8. Check the Frontier Airlines app permissions. You need to permit Frontier Airlines to access things like your contacts, photos, mic, etc., otherwise, those things won’t work. (Android, iPhone)

9. Uninstall and reinstall the Frontier Airlines app. If nothing else has worked to this point, take the time to completely uninstall Frontier Airlines from your Android or iPhone. Then reinstall the Frontier Airlines app on your device.

10. Free-up space on your phone. A lack of free space can often cause apps to crash or not open. The process of freeing up storage space depends on your platform: Android, or iPhone.

11. Disable your VPN service. A VPN is a great service for protecting your privacy and increasing security. Unfortunately, a VPN can also cause connection errors and lead to Frontier Airlines not working. To test if this is the case, disable your VPN on Android device or disable your VPN on iPhone and check if this resolves the issue.

12. Make sure background data is not restricted. If Background data is turned off, Frontier Airlines may not be able to connect to the internet while it’s running in the background. To fix this, you need to turn on the background data on Android or turn on the background data on iPhone.

13. Reset your iPhone’s app settings or reset app settings on your Android device. This action does not delete any of your apps or their data. It reverts app-specific settings to their default values. This can include preferences like notification settings, permissions, background app refresh settings, and other app-specific configurations.

14. Reset your phone’s network settings. If the Frontier Airlines app is having trouble connecting to the Frontier Airlines servers, performing a network settings reset on your Android device or network settings reset on your iPhone could fix it.

15. Update your iPhone or Update your Android device. Downloading and installing the latest iOS or Android operating system can fix a variety of system and app issues.

16. If all else fails, it may be time to report the issue to Frontier Airlines. It could be an issue with your account, and Frontier Airlines customer support should be able to help you determine if that’s the case.
