How we work
At ClaimWinger, cases are handled in-house.
This means that:
- case assessment,
- document preparation,
- communication with airlines,
- legal proceedings (when required)
are carried out by our own legal and operational team rather than outsourced to third-party intermediaries.
This gives you:
- one accountable partner,
- a more transparent and controlled process,
- better data protection.
Our specialization
We focus exclusively on airline passenger claims, including:
- flight delays,
- flight cancellations,
- denied boarding,
- missed connections,
- overbooking.
This is a highly specialized legal area, and it is the only field we operate in.
