Is There a Class Action Against Marriott in 2026?

Updated August 11, 2026 · By Class Action Buddy

The short answer: the big one was won on appeal — by Marriott

Yes, class actions against Marriott exist, and one of them settled. But the case most people are looking for — the Starwood data breach — went the other way. In June 2025 the Fourth Circuit reversed, and the mandate issued on 25 June 2025.

The second thing worth knowing is that Marriott’s own loyalty programme contains a class-action waiver, and a federal court has already ordered the parties to brief what it does to a class claim.

What the record actually shows

Peter Maldini v. Marriott International, Incorporated is the appeal that matters. Its originating case number is 8:19-md-02879 — In Re: Marriott International, Inc., Customer Data Security Breach Litigation in the District of Maryland, confirmed on the docket. On 3 June 2025 the Fourth Circuit entered a judgment order recorded on the docket in one word: “Decision: Reversed”, with a published authored opinion. The mandate issued 25 June 2025.

The class-waiver point is not speculation either. In Vetter v. Marriott International, Inc. — a case with 179 named parties — the court entered an order on 22 September 2023 directing the plaintiffs and Marriott to brief the effect of the class waiver provision contained in the Starwood Preferred Guest programme. The loyalty terms are not background detail in these cases; they are the battleground.

That waiver is still in the programme rules today, and any Bonvoy member has already agreed to it.

Marriott’s Bonvoy Program Rules, section 14, say this:

“Any disputes arising out of or related to the Loyalty Program or these Program Rules will be handled individually without any class action”

— Marriott Bonvoy Program Rules, §14, read on 11 August 2026.

Cases on the public record

Each of these was matched on case name in the federal docket on 11 August 2026, and each links to its own record so you can read it yourself. Docket numbers repeat across districts, so a number on its own proves nothing — the case name is what identifies a case.

Where the status comes from. These are read from each docket’s own entries, not from a summary elsewhere. Two limits are worth knowing. The public docket mirror does not carry the text of every entry, so where an entry has no description this page says what it can date rather than invent what it said. And a case with no termination date on file is unknown, not open — a blank field is not a finding.

What we removed, and why. An earlier version of this page listed a “Starwood data breach consumer class action” and an “FTC & multistate AG data-security settlement”. Not one carried a case name, a court or a docket number, and none could be matched to a federal docket. They are gone. A claim you cannot check is worth less than no claim at all.

What you can actually do

1. Read section 14 of the Bonvoy Program Rules before anything else. It is the provision a federal court has already ordered briefing on. If you are a Bonvoy member, it is the single document most likely to decide whether a class claim is available to you at all.

2. Do not assume the breach litigation is still running. The Fourth Circuit reversed in June 2025. Anything you read that describes a certified Marriott breach class without mentioning that reversal is out of date.

3. Keep your breach notification letter if you got one. It records which of your data was involved and when, which is what any future claims process would ask for.

4. Ignore anyone charging to “sign you up”. Joining a class costs nothing and filing in a real settlement is free.

How we checked this page

Verified on 11 August 2026. Cases were found by searching the federal docket for Marriott’s corporate name, then each docket was opened and its entries read for the events that decide a class action — certification, dismissal, settlement approval, remand. Where this page describes a court’s decision it quotes the docket entry recording it, and the loyalty-programme wording was read from Marriott’s own site on the date above. We publish what the record shows and say plainly where it stops.

Frequently Asked Questions

Can I still join the Marriott data breach class action?

The Fourth Circuit reversed on 3 June 2025 in Peter Maldini v. Marriott International, Incorporated, whose originating case is the Marriott data-breach MDL 8:19-md-02879-PWG in Maryland, and the mandate issued on 25 June 2025. There is no open claims process for it listed on this page.

Does Marriott Bonvoy stop me bringing a class action?

Section 14 of the Bonvoy Program Rules says disputes related to the loyalty programme “will be handled individually without any class action”. A federal court has already ordered briefing on what that waiver does — in Vetter v. Marriott International, Inc., on 22 September 2023 — so its effect is contested rather than settled.

Has any Marriott class action actually settled?

Yes. Hall v. Marriott International, Inc. received an order granting final approval of a class action settlement on 10 July 2024, and Emma Hart v. Marriott International, Inc. received final approval on 24 June 2019. Both are linked above with their dockets.

What does “reversed” mean for me as a class member?

It means the appeal court set aside the decision below. It does not automatically end the underlying litigation, but it does mean any description of the case that predates June 2025 is describing a position that no longer stands.

Is there anything to file right now?

Not from the cases on this page. A settlement only becomes claimable once a court approves it and an administrator opens a claims process with a published deadline. If those three things do not exist, there is nothing to file, whatever a listing site says.
