AC Dispute resolution advice
I have a dispute with Air Canada over a cancelled flight, Three months ago they offered a voucher in compensation which I advised I did not find acceptable, I have contacted them every month since then and nothing heard.
The flight was domestically in Canada although part of a booking from the EU, I thought about contacting Aviation ADR but am less than impressed by the reviews or their success rate.
Where should I go next? Thinking the Canadian Transport Authority although I know that takes ages and may not provide an answer even if the ruling is in my favour?.
What advice can you give please?
