International travel

Preparations for international travel

International travel doesn’t have to be tricky – just make sure your travel documents and required paperwork are in order. When you travel internationally, you’re responsible to make sure you have the correct documents to enter and pass through any countries during your trip, and then make your way back home.

To start:

Travel requirements and documents

Make sure to check entry requirements with the consulate of the countries you plan to visit before you travel. You’re responsible for bringing the correct documents for international travel. If you don’t have the required documentation and identification, you will not be allowed to board the plane and would be responsible for any resulting costs.


A passport is required for all international travel. If you're traveling anywhere overseas, you need a passport to board an international flight and to enter the country. Passport cards will not be accepted as form of I.D. for international air travel.

Passports must be:

U.S. citizens can use any government-issued form of identification to travel between the U.S., Puerto Rico and the U.S. Virgin Islands.

Visa and Visa Waiver Program

In addition to a passport, some countries require a visa to enter. If you’re traveling to the U.S. for a stay less than 90 days, the Department of Homeland Security requires eligible travelers to use the Electronic System for Travel Authorization (ESTA), as part of the Visa Waiver Program (VWP). You can submit your application any time before you travel, but we suggest that you apply for authorization when you start planning your trip to the U.S. In most cases, ESTA will provide an immediate determination of eligibility for the VWP.

An approved ESTA travel authorization is:

To enter the U.S. under the VWP, each passenger must have a machine-readable passport. If you don’t have a machine-readable zone, a valid visa is required

Traveling from Chile?

Under the VWP, Nationals of Chile traveling to the U.S. are required to have an E-passport in addition to a machine-readable passport.

Traveling to Australia?

Health requirements

To travel, vaccinations may be required depending on where you’re traveling to and from.

Tax exemptions

If your itinerary involves travel between the U.S. and Mexico (including travel between Canada and Mexico via the U.S.) and you meet the applicable criteria for exemptions, you may be entitled to a refund of the Mexico Tourism Tax and/or the Mexico Airport Departure Tax included in the price of your ticket.

U.S. Customs and Border Protection

Learn about regulations and procedures that apply to all travelers that enter or depart the United States.

Advanced Passenger Information (API)

To enhance border security, passenger information will be passed through the Advanced Passenger Information (API) system and sent to U.S. Customs and Border Protection to review passenger information before the flight arrives.

US-VISIT program

All visitors to the U.S., except nationals of Canada, will have their photograph and fingerprints taken, and will automatically be registered under the US-VISIT program when they pass through Customs and Border Protection.

TSA Secure Flight Passenger Data

Secure Flight Passenger Data is basic personal information the TSA requires for you to travel. The information is collected during booking or ticketing.

International travel with infants and children

To travel internationally, all children, regardless of age, must have a passport and any travel documents required by the countries visited. If you’re traveling internationally with anyone under 18, you may be required show documentary evidence of your relationship and a Letter of Consent or permission for the child's travel from the parent(s) or legal guardian not present.
