Hello! I understand that you're having trouble finding one of your cruises in the app to check in. Let's work together to resolve this issue.

To start, could you please let me know if you've made sure that you are logged into the same account you used to book both cruises? Sometimes, being logged into a different account can lead to bookings not showing up.

If you're in the correct account, here are a few steps you can take:

1. Refresh the App: Close the Celebrity Cruises app completely and then reopen it to see if the cruise appears.

2. Check Trip Details: Go to the "My Trips" section within the app. If you don't see your cruise listed there, try navigating to "Browse our ships," select your ship, and then the date of your cruise. This has helped other users find their bookings1.

3. Verify Email Confirmation: Double-check your email confirmation for the missing cruise. Ensure that it matches the email address associated with your app account.

4. Update the App: Check if your app is up to date. Sometimes, an outdated version can cause display issues.

If these steps don’t help, I recommend reaching out to our support team directly for additional assistance. You can email them at [email protected] or [email protected].

Are you satisfied with the solutions I've provided, or would you like to try something else?
