My wife had travel booked YYT-ABZ this month, booked via RBC Avion points. She received several emails from AC advising of change of flight times and routing - but strangely nothing on the fact that the LHR-ABZ flight was operated by an airline (FlyBe) that had ceased trading - culminating in the cancellation of her return flight. (originally booked as LHR-YYT). After several tortuous phone calls with Avion where they cited that they could cancel the flight by AC would still charge $300 cancellation, yesterday she was offered cancellation, refund of moneys, less the cancellation fee & points and that the cancellation fee would be refund in 8 weeks or so as AC had cancelled the flights. So I assume that's a similar situation to AC direct booked flights now being refunded but taking 8 weeks or so.
