UK CAA Complaint Process Explained

The UK Civil Aviation Authority (CAA) is the enforcement body for UK261, ACAA-equivalent disability rights, and other UK-departure passenger rules. Here is the full 2026 complaint process, timelines, and what the CAA can actually do for your claim.

What the CAA Does

A UK CAA complaint airline process handles post-Brexit UK261 claims and disability passenger rights under the UK Air Passenger Rights regulations. The CAA can investigate, issue enforcement orders, and refer cases to Approved Dispute Resolution (ADR) schemes. Individual passenger compensation generally comes through the airline's response to CAA inquiry or through ADR mediation, not directly from the CAA.

CAA does not award individual compensation directly. It investigates violations and applies enforcement pressure. For binding individual rulings, ADR schemes (AviationADR, CEDR) are the faster path if your airline is a member.

When to File a CAA Complaint

  1. 1

    After the airline has denied in writing, or gone silent for 8+ weeks.

  2. 2

    For ongoing pattern violations where you have multiple documented cases.

  3. 3

    When ADR is not available (airline is not an ADR member).

  4. 4

    As a backup to court action to apply enforcement pressure while litigation proceeds.

Filing the CAA Complaint

  1. 1

    Collect documentation: flight details, airline denial letter, copies of original complaint.

  2. 2

    Email: passengers.complaints@caa.co.uk.

  3. 3

    Include the standard information: flight number, date, route, nature of disruption, regulatory basis, amount claimed.

  4. 4

    Attach supporting documents: boarding passes, booking confirmation, airline correspondence.

  5. 5

    Cite the specific regulation: UK Air Passenger Rights (UK261), ACAA equivalent, or other applicable rule.

  6. 6

    State what you want: compensation amount, refund, rebooking.

  7. 7

    Submit: CAA acknowledges within 7 days and opens a case.

CAA Response Timeline

Typical CAA complaint timeline:

  • Week 1: acknowledgment, case number issued.

  • Week 2 to 4: CAA contacts airline for response.

  • Week 4 to 8: airline responds; CAA reviews.

  • Week 8 to 12: CAA rules or refers to ADR.

  • Week 12 to 16: airline compliance (if ruled against).

Aggregate CAA response time in 2025 was 8 to 12 weeks for most cases.

ADR Alternatives

If the airline is a member of an Approved Dispute Resolution scheme, you can bypass CAA and go direct to ADR:

  • AviationADR: member airlines include easyJet, Wizz Air, Jet2, Loganair, TUI Airways. Response 6 to 12 weeks; binding on airline.

  • CEDR: member airlines include British Airways. Response 8 to 14 weeks; binding.

  • Non-members: complaint goes to CAA.

See UK small claims court for UK261 claims for the court alternative.

What the CAA Enforces

  • UK261 compensation and refund rights.

  • Duty of care obligations (meals, hotels, rebooking).

  • ACAA-equivalent disability protections.

  • Accessibility requirements for airports and airlines.

  • General CAA oversight of airline operations and licensing (licensing breaches can trigger enforcement action).
