Keep the contract confirmation, standard information form, local contact details and travel itinerary. Add a chronology showing when the difficulty arose, each contact attempt, the information received, alternatives offered and services actually booked. Messages, call records, receipts and authority reference numbers should be linked to the relevant event.
Report the difficulty through the contact point named in the contract and keep the message. If a phone call does not produce a sufficient solution, summarise the content and open issues in writing. In a medical emergency, after a document loss or before an imminent departure, the relevant emergency service or authority must be contacted first.
A legal assessment should distinguish the personal difficulty, a non-conformity in the travel service, the assistance offered, the actual costs and any further claim. Advice may then examine whether rights arise from deficient services, return transport or insurance in addition to the assistance duty.
