Passport Requirements for International Travel
All persons, including U.S. citizens, traveling by air between the United States and Canada, Mexico, Central and South America, the Caribbean, and Bermuda will be required to present a valid passport. Passports will also be required for re-entry to the United States. Passports are not required for travel to Puerto Rico or the U.S. Virgin Islands. You do need to carry a non-expired government-issued photo ID that matches the name on the reservation.
