The United States government’s Secure Flight program requires airlines to collect specific information about all passengers travelling to, from or via the United States.
This is known as Advanced Passenger Information (APIS) and includes gender, date of birth and name exactly as it appears on your passport.
APIS details for all travellers must be provided no later than 72 hours prior to departure or you may be denied boarding.
For bookings made less than 72 hours before departure, APIS information must be provided at the time of booking.
If you have a Redress control number, this must be provided along with the personal details.
Residents of countries that are part of the Visa Waiver Agreement are allowed to travel to the United States without a visa.
However, you must have an ESTA authorization (Electronic System for Travel Authorization).
Without ESTA authorization, passengers cannot be allowed to board their flight to the USA, even if you are simply travelling via the USA.
To enter the United States, you must have applied for ESTA authorization no later than 72 hours before your departure.
If you are travelling without ESTA authorization, you may be denied entry to the United States upon arrival.
To apply for ESTA, you need an electronic passport. Electronic passports are printed with an icon on the front. If you are unsure which passport you have, contact the Greenlandic or Danish authorities.
As a traveller, it is your responsibility to apply for ESTA authorization

ESTA authorisations are often granted for a period of 2 years or until the applicant’s passport expires.

Non-Disclosure Agreement (NDA)
The U.S. Transportation Security Administration (TSA) requires you to provide your full name, date of birth, and gender for the purpose of screening for a watch list under 49 U.S.C. section 114 of the Intelligence Reform and Terrorism Prevention Act of 2004 and 49 C.F.R. sections 1540 and 1560.
You can also provide your Redress number if applicable.
Failure to provide full name, date of birth and gender may result in refusal of transport or denial of access to the boarding area by authorities.
The TSA may share the information you provide with law enforcement or security authorities or others under their designated information sharing system.
You can read more about the TSA’s privacy policies or review the information sharing and privacy impact assessment system at the TSA’s website
Address of your accommodation
At check-in at the latest, you must provide the address of your first accommodation in the United States - this also applies if you are only travelling through the United States.
