An Online Dispute Resolution (ODR) platform has been set up by the European Commission: http://ec.europa.eu/consumers/odr/
which provides easy access to alternative dispute resolution(ADR). Please note that Air Transat is not currently subscribed to an approved
ADR scheme therefore neither the ODR platform nor any approved ADR providers will be able to accept your complaint.
You can log your complaint with CAA’s Passenger Advice and Complaints Team (PACT) by completing the online complaint form via the CAA
Under the subtitle ‘How the CAA can help’ you will need to click on the link ‘Refer your complaint to us’.
You can then access the CAA’s consumer portal where you can submit your complaint to PACT.
