Effective January 8, 2007, all customers traveling by air or sea to/from the U.S. will be required to have a passport. This is a change from prior travel requirements which in many cases allowed travel with a driver's license or birth certificate. The goal is to strengthen border security and facilitate entry into the United States for U.S. citizens and legitimate foreign visitors. Review the complete details. In addition, each passenger desiring transportation across any international boundary is responsible for obtaining all necessary travel documents and for complying with the laws of each country flown from, through or into which he or she desires transportation as stated in Rule 19 of the Contract of Carriage.
