What happened?

In April 2026 a criminal group said it held a large amount of the company's data and tried to extort it. A week later the group made the data public. It related to the loyalty program of Holland America, one of the company's cruise brands, and held names, email addresses, birth dates, genders and loyalty status. The company acknowledged a phishing incident affecting one user account and said it was still working out the scope.

What was exposed, and what does it mean for me?

  • Identity detailsdates of birth

    A date of birth is one of the facts a lender or a phone company uses to confirm who you are. It does not change, so it stays useful to a fraudster for years.

  • Your email addressemail addresses

    Expect messages that look like they come from this service or another one you use, written to get you to click a link or sign in on a fake page.

  • Other detailsgenders, general locations, loyalty program details, names and salutations

    On their own these carry less risk, but they make a scam message sound more personal.

What should I do now?

In this order, for what this breach exposed.

1. In the US: freeze your credit at all three bureaus

  • Place a credit freeze with Equifax, Experian and TransUnion. It is free to place and to lift, and it does not affect your credit score.
  • If you would rather not freeze, a fraud alert lasts one year. You ask one bureau and it tells the other two.
  • If someone uses your details, report it at IdentityTheft.gov to get a recovery plan.

2. In Canada: check your credit file and lock it

  • Get your credit report from Equifax Canada and TransUnion Canada. Both give it free online.
  • In Ontario, both bureaus must offer a security freeze free of charge, and each bureau is a separate request.
  • If you live in Quebec or Ontario, Equifax Canada will lock your credit report at no charge, online, by phone or by mail. Ask TransUnion Canada separately.
  • If your details are used to open an account, call your bank, report it to both bureaus, report it to your local police and get a file number, then report it to the Canadian Anti-Fraud Centre (1-888-495-8501).

3. Expect phishing

  • Be wary of messages that urge you to act fast, ask for personal details, or link to an address that is slightly off.
  • If a message might be genuine, do not use its links or phone numbers. Go to the site by typing its address yourself.
