Users submit flight and disruption details through an online portal, which checks eligibility, estimates possible compensation, and prepares claims. ClaimCatalyst then manages communication with airlines, including documentation, follow up, and structured submissions to customer service, regulatory bodies, or dispute resolution schemes. When necessary, the service escalates matters to enforcement authorities or coordinates litigation, using a tiered success-fee model with no upfront cost. The platform incorporates data and evidence collection, including flight operations and weather information, to support claim assessment and enforcement.
