Hi! I’m sorry to hear you’re seeing a blank screen when trying to log into the American Airlines app on your iPhone. Let’s see if we can get this sorted out together.

Since you mentioned you've already tried the usual steps, just to double-check, could you tell me which troubleshooting steps you’ve already attempted? For example, have you tried restarting your phone, updating the app, or reinstalling it?

In the meantime, here are some steps that often help with blank screen issues on iOS apps:

1. Force Close and Reopen the App:
- Swipe up from the bottom of your iPhone screen and pause (or double-click the Home button if your model has one).
- Swipe the American Airlines app off the screen to close it completely.
- Then open the app again to see if it loads normally.

2. Check for App Updates:
- Open the App Store, tap your profile icon at the top right, and scroll down to see if the American Airlines app has an update pending. If so, install the update.

3. Restart Your iPhone:
- Hold the side button and either volume button until the slider appears, slide to power off, then turn your phone back on after a minute.

4. Reinstall the App:
- Press and hold the American Airlines app icon, tap "Remove App," then "Delete App."
- After that, reinstall it fresh from the App Store.

5. Check Your Internet Connection:
- Sometimes a poor Wi-Fi or cellular connection can cause loading issues. Switching between Wi-Fi and cellular data or toggling Airplane Mode on and off might help.

If you’ve gone through these already, we can dig deeper—perhaps there’s an account or iOS version-specific detail causing this. Your iOS version 26_2_1 is quite recent, so compatibility should not be an issue, but sometimes glitches occur.

Could you also let me know if the blank screen appears right after launching the app, or specifically after entering your login details? That information can help pinpoint the cause.

Let me know, and we’ll take it from there!
