Secure Flight & APIS
The US government’s Secure Flight program requires airlines to collect specific information about all passengers travelling to, from or via the USA.
This is known as Advanced Passenger Information (APIS), and includes gender, date of birth, and name exactly as stated in your passport.
APIS must be submitted no later than 72 hours before departure; otherwise, you may be denied boarding. For bookings made less than 72 hours before departure, the information must be provided at the time of booking.
If you have a Redress Number, this must also be provided along with your personal information.
ESTA – Travel Authorization to the USA
Travellers from countries participating in the Visa Waiver Program can travel to the USA without a visa, but must have a valid ESTA approval – an additional travel authorization.
Important to know:
• You must apply for ESTA no later than 72 hours before departure.
• Without an approved ESTA, you cannot board the aircraft – including when transiting through the USA.
• You must have an electronic passport to apply.
• It is your own responsibility to apply for ESTA.
Electronic passports are marked with an icon on the front. If you are unsure which type of passport you have, please contact the Greenlandic or Danish authorities.

An ESTA approval is normally valid for 2 years or until your passport expires.
