Hi there! I understand your Alaska Airlines app is not showing your reservations, and I’m here to help you get that sorted out. To assist you better, could you please let me know:

1. Have you recently booked the reservation through the app or through a different website?
2. Are you logged into the app with the same Alaska Mileage Plan account that you used when booking?
3. Have you tried refreshing the app or logging out and back in?
4. Do you see any error messages when you try to view your reservations?

While you provide those details, here are some general steps you can try to resolve this issue:

1. Confirm Login: Make sure you are logged into the Alaska Airlines app with the correct Mileage Plan account—the one you used to book the flight.

2. Refresh the App: Close the app completely and reopen it. Sometimes, this refreshes your reservation list.

3. Manual Add: If your reservation does not appear automatically, try manually adding your reservation using your confirmation number and last name in the app’s “Add a reservation” section.

4. Check Online: Use a mobile browser and go to Alaska Airlines’ reservation page at https://m.alaskaair.com/cancel to verify if your reservation shows there. This can help indicate if it's an app-specific problem or account-related.

5. Update the App: Ensure your app is updated to the latest version from your app store, as outdated versions can cause syncing issues.

6. Clear Cache: If possible on your device, clear the app’s cache or reinstall the app to remove corrupted temporary files.

If you've already tried these steps or if the problem persists, please let me know what you’ve tried and I can guide you through more advanced troubleshooting or verify if there's a known issue with your booking.

Does this work for you so far?
