It really would be helpful if Continental would update the FAQ page regarding online check-in to remove this uncertainty regarding proper formatting of account names, kiosk scanning of your passport, and the length of time that this scan remains valid for. A simple, but accurate, list of eligibility requirements for International Online Check-In would be perfect.

Additionally, while I am uncertain about departures from Shannon, flights originating in Dublin have been able to use online check-in since the summer of 2008.
