Requirements for flights to and from Canada, the United Kingdom and the United States.

Three countries within the Icelandair route network require certain passenger information to be transmitted prior to departure for all flights to and from the country. These are the United States, Canada and the United Kingdom.

This information is generally referred to as Advance Passenger Information (API) or Travel Document Information (TDI). This is the information that is displayed on the bio-data page of your passport. API is gathered at check-in for flights to Canada and the United Kingdom.

The U.S. requires more advance on certain data elements. Advance Passenger Information System (APIS) is API information required by U.S. authorities of all persons travelling to and from the country. All air carriers, including Icelandair, are bound by law to transmit API/APIS information prior to departure. Passengers must provide this information or risk being denied passage.

ATTENTION: We kindly ask passengers who are traveling to and from the United States to use the electronic APIS to update their API/APIS information, if it has not already been done during reservation. You can provide and update your APIS information via Manage Your Booking.

For travel to and from Canada and the United Kingdom, the API information is completed at check-in.

Travelers should submit the application online at least 72 hours prior to departure. In most cases, the application is handled immediately, and you will receive an instant answer online.

All Visa Waiver Program travelers to the US will be required to pay a fee when submitting their ESTA application through the ESTA website. Credit card or debit card payment is required.

Once the application has been approved, the ESTA will typically be valid for two years
