I got this email this morning, Cunard says I'm missing "Emergency Full Address, US Address while in US". I suspect it's the emergency contact info they want me to complete, but I'm Canadian and all my travel information indicates as such. I suspect their system sees the "state" field as left blank and thinks my emergency contact information isn't complete, but the state field is only displayed if you select United States as the country, Canada has no option to indicate a province.
I suppose I'll have to call Cunard to get this sorted out.
