One million British travellers planning to fly to Canada, the Caribbean and Mexico this year face the risk of being turned away at the airport – at the insistence of the US Department of Homeland Security.
New rules require British Airways and other airlines flying to certain airports outside America to submit passengers' personal data to US authorities. The information is checked against a "No Fly" list containing tens of thousands of names. Even if the flight plan steers well clear of US territory, travellers whom the Americans regard as suspicious will be denied boarding.
Now the US is demanding passengers' full names, dates of birth and gender from airlines, at least 72 hour before departure from the UK to Canada. The initial requirement is for flights to Toronto, Ottawa, Montreal and the Nova Scotia capital, Halifax – 150 miles from the nearest US territory. A similar stipulation is expected soon for the main airports in western Canada, Vancouver and Calgary.
Any passenger who refuses to comply will be denied boarding.http://www.independent.co.uk/travel...immigration-may-have-other-ideas-7584912.html

So if you were thinking of vacationing in Cuba, better take a boat.
