Escalation and evidence

If you do not get a satisfactory response, you can escalate. The right route depends on the sector and whether the firm uses an ADR/ombudsman scheme.

  • Sector: airlines
  • Regulator / ombudsman / ADR: Relevant ADR/aviation dispute route; UK context: Civil Aviation Authority (CAA)
  • Typical wait before escalation: Allow the airline time to investigate; escalate if you receive a deadlock response or prolonged non-response.
  • Evidence that helps: Booking reference, flight number(s), travel dates, receipts, screenshots of notifications, and any written correspondence.

Your letter should request a written response and set a reasonable deadline.
