Guests will need their booking reservation numbers to complete the Celebrity cruise online check-in. Booking numbers are not sent until approximately 30-60 days before sailing. You will need this number in order to log in and complete your online check-in for the cruise, as well as to print your boarding pass and eDocs. If this is your first time sailing on a Celebrity cruise, you must create a new account before checking in. For those that have sailed on Celebrity before, you’ll need to login with your existing account information. Guests are requested to complete online check in no later than three days prior to the cruise. It is also important that you complete your online check in to confirm that the cruise line has your correct information, otherwise this could result in denied boarding.
