Travel documents, including passports, visas, and health/vaccination certificates required are your responsibility. Valid passports are absolutely required for all international destinations and the expiration date should be at least 6 months following the return date of your trip. Some countries require that your passport have two to four blank visa/stamp pages. Some airlines will not allow you to board if this requirement is not met. See this State.gov link for passport support. When travelling domestically or internationally, the U.S. Transportation Security Administration (TSA) and U.S. Department of Homeland Security (DHS) advise that everyone carry at least two forms of acceptable identification in order to board a flight. (See this link.) Examples: DHS designated enhanced driver’s license, USA Passport, a foreign government passport. The name, date of birth and gender that appears on the identification card must exactly match the same such data that is listed on airline ticket(s) and booking records.
