Which airlines owe travellers the most?

No regulator publishes how much compensation each airline owes or pays, so we don't guess. The closest official measure in Canada is the number of complaints passengers file with the Canadian Transportation Agency after failing to resolve a problem with the airline. Here it is, per 100 flights, exactly as the CTA published it.

How to read this data

  • Only airlines averaging 1 or more complaints per 100 flights to, from or within Canada in at least one quarter, and operating at least 100 flights, are listed.
  • Complaints are submitted by passengers after unsuccessful resolution with the airline. They may not have been reviewed yet, and inclusion does not necessarily mean the airline broke the rules.
  • The rate is per flight, not per passenger, so it doesn't reflect aircraft size.
  • Accessibility complaints are not included. Flight counts come from a third party (Cirium).

A complaint isn't the same as money owed: it can be about refunds, delays, baggage or service. For what you may be owed on a specific flight, use the APPR calculator.
