Hi there! I see you're encountering a blank screen when using the Alaska Airlines app on your iPhone running iOS 18.6. I’d like to help get that sorted out.

To start, could you let me know:
- When did the issue begin?
- Have you tried any troubleshooting steps already, like closing and reopening the app, or reinstalling it?
- Does the blank screen show immediately on launch, or when you try to do a specific action (like logging in or checking flights)?

In the meantime, here’s a quick checklist of steps to try, if you haven’t already:

1. Force-close the app: Swipe up from the bottom of the screen and pause, then swipe the Alaska Airlines app off the screen to close it completely. Open it again.
2. Restart your iPhone: Hold the side button and either volume button until the power off slider appears; power off, then power back on.
3. Check for app updates: Open the App Store, tap your profile icon, and scroll to see if there’s an update for the Alaska Airlines app. Install any available updates.
4. Reinstall the app: Delete the app by pressing and holding it, then tap Remove App > Delete App. Reinstall it fresh from the App Store.
5. Wait briefly before interacting after reinstalling: Some users found that after reinstalling, not tapping buttons right away can help the app load properly6.

If you’ve tried the above and the app still shows a blank screen, it could be related to server or connectivity issues on Alaska Airlines’ end, or maybe even a recent update glitch2.

Let me know what you’ve tried, and how the app behaves now, so I can guide you further!
