Travel Documentation and Other International Travel Requirements   

When planning international travel, travel documentation is very important. Please ensure that your customers are in possession of all required documents for both outbound and return flights.

International Travel Documentation

Documentation and entry requirements are different for every country. Prior to travel, Delta recommends that travel professionals check the passport, visa & health travel document requirements for each country.


A passport is required for all international travel. A passport is required to board an international flight and to enter any country. In general, a passport must be valid for at least six months after the date of entry into a foreign country.

Visit the U. S. State Department's website for information on obtaining first time passports, passport renewals, second passport issuance and extra blank pages for an existing passport. 


A travel visa is required to enter many countries. For information regarding countries that require a visa, visit TravelCentre for more information.

Advanced Passenger Information (API) 

To enhance border security, electronic transmission of passenger information through the Advanced Passenger Information (API) system has been mandated with the U.S. Aviation and Transportation Security Act. All passengers entering/departing the U.S. by air are required to have this information transmitted to U.S. Customs and Border Protection (CBP), allowing U.S. CBP to review all passenger data in advance of the flight's arrival. All international flights arriving and departing the U.S. are required by law to provide API data. API data is also transmitted to Customs and Immigration Officials in all other countries when required by law.

U.S. Entry/Exit Requirements for Non-U.S. Citizens

Visa Waiver Program
  • The Visa Waiver Program (VWP) requires travelers to submit an online request for travel authorization via the Electronic System for Travel Authorization (ESTA), prior to boarding a carrier to travel by air or sea to the United States. This allows visitors from participating countries to get speedy approval for travel to the U.S. for business or pleasure for 90 days or less without first obtaining a visa.

Electronic System for Travel Authorization (ESTA) for Visa Waiver Program Travelers
  • For travel to or connecting through the U.S., the U.S. Department of Homeland Security (DHS) requires all Visa Waiver Program (VWP) nationals to obtain an electronic travel authorization prior to boarding.

Global Entry

Global Entry is a program developed by the U.S. Customs and Border Protection to expedite entry into the U.S. for low-risk, pre-screened international travelers. Upon arriving in the U.S., members proceed directly to the automated Global Entry kiosk — bypassing passport control lines and paper customs declarations.

Global Entry is now available at over 40 major U.S. airports. For a complete list of locations you can visit the Global Entry website.

A non-refundable application fee of $100 per applicant will be charged at the time of application. If approved, membership is valid for five years. Here's how the application/approval process works:

1.       Complete an application online and pay the non-refundable application fee

2.       If conditionally approved after review, U.S. Customs and Border Protection will follow up to schedule an interview at an in-airport enrollment center. Alternatively you may complete your interview on your next international arrival at selected airports. For a list of approved locations visit Global Entry on Arrival.

3.       Participate in the in-person interview during which a U.S. Customs and Border Protection officer will review the application and verify identification documents and eligibility.

4.       If approved, the officer will take the member’s photo, obtain fingerprint information, and introduce the new member to the program.
