Hi! I’m sorry to hear the MileagePlus X app isn’t loading properly when you select MileagePlus, and instead you’re having to use Delta Airlines shopping. Let’s get this sorted out together.

To help you better, could you tell me if you’re using the MileagePlus X app on your Windows device’s browser (WebKit)? Also, do you see any error messages, or does it just stay stuck or show a blank page when you click MileagePlus?

Meanwhile, here are some straightforward steps you can try to fix this issue on your Windows 10 browser:

1. Clear Browser Cache and Cookies: Sometimes, stored data causes loading issues.
- Open your browser settings.
- Find the section to clear browsing data.
- Select to clear cache and cookies.
- Close and reopen the browser, then try again.

2. Enable Cookies and Check Browser Settings: Make sure your browser allows cookies from the MileagePlus site, as blocking them can prevent the site from loading properly.

3. Try Using a Different Browser: If you have another browser installed, check if the problem happens there too. This helps identify if the issue is browser-specific.

4. Disable Browser Extensions: Some ad-blockers or privacy extensions can interfere with site loading. Try disabling them temporarily and see if MileagePlus loads.

5. Update Your Browser: Ensure your WebKit-based browser is up to date to avoid compatibility problems.

If after these steps, the issue remains—such as blank screens or errors on loading MileagePlus—I can help guide you through some advanced troubleshooting or recommend contacting MileagePlus support directly via the app's “Contact Us” form in the “Buy eGift Cards” section or by email at [email protected]1.

Let me know how these steps go and if you notice any error messages, so I can assist further! Are you satisfied with this initial approach?
