FMC CADRS: The Free Government Service That Pressures Cruise Lines to Respond
Most cruise passengers have never heard of FMC CADRS. That is exactly why cruise lines love it when you haven't — because the threat of a CADRS complaint is one of the most effective tools a passenger has.
What Is FMC CADRS?
FMC CADRS stands for the Federal Maritime Commission's Office of Consumer Affairs and Dispute Resolution Services. It is a US government office that mediates disputes between cruise passengers and cruise lines — completely free of charge.
The FMC is the federal agency responsible for regulating ocean shipping in the United States. Cruise lines operating from US ports must be licensed by the FMC, which gives the FMC significant leverage over them.
What CADRS Can Help With
- Billing disputes and unauthorized charges
- Missed ports and itinerary changes
- Mechanical failures and service disruptions
- Refund requests that have been ignored
- Cabin and accommodation complaints
- Shore excursion failures
💡 CADRS does not have the power to force a cruise line to pay you — but it can formally contact the cruise line on your behalf, which cruise lines take very seriously given the FMC's regulatory authority over them.
How to File a CADRS Complaint
- Send a formal complaint letter to the cruise line first — give them 14 to 30 days to respond
- If they do not respond satisfactorily, email your complaint to support@cruisecomplaintletter.com
- Include your full name, booking details, the cruise line's name, a description of the issue, and what compensation you are seeking
- Attach copies of any documentation — receipts, onboard complaint records, cruise line correspondence
- CADRS will contact the cruise line and attempt to mediate a resolution
Why Mentioning CADRS in Your Letter Works
Simply stating in your complaint letter that you will escalate to FMC CADRS within 30 days if no resolution is reached often prompts a response from cruise lines that would otherwise ignore you. Guest relations departments know that a CADRS complaint creates regulatory visibility they would rather avoid.
CADRS vs. Filing a Lawsuit
CADRS mediation is free, fast, and requires no attorney. A lawsuit is expensive, slow, and uncertain. For most cruise complaints under $10,000, CADRS is the more practical path. For larger claims involving personal injury, consult a maritime attorney.
Can international passengers use FMC CADRS?
CADRS is most effective for complaints involving cruises that departed from US ports, regardless of passenger nationality. If your cruise departed from a non-US port, CADRS may still accept your complaint but its leverage is more limited. Non-US passengers should also contact their own national consumer protection agency.
How long does CADRS take?
Most CADRS mediations are resolved within 60 to 90 days. Some are faster if the cruise line responds promptly to the FMC's inquiry.
