U.S. government warns cruise passengers: 'You will need your passport book'

The U.S. Department of State is advising all travelers on international cruises to carry their passport books, not just cards. This recommendation is particularly important for unexpected situations that may require immediate air travel from a foreign port.

According to the State Department, a passport book is essential if a medical or family emergency arises during an international cruise, necessitating a flight home. Without a passport book, individuals may be unable to board an international flight, potentially causing significant delays and complications in returning to the United States.

While a passport card may suffice for boarding the cruise itself, it has limited use for international air travel. The department emphasizes that the passport book is the only reliable document for ensuring a swift return via air in unforeseen circumstances. Travelers are also advised to consult with their cruise line about emergency procedures, family contact methods at sea, and available onboard medical services.
