I cancelled a redemption booking on March 13...travel was the next day (the flight still operated). I did the cancellation online, but it seems like this is only really a request to cancel...the booking remained confirmed and ticketed up until and after the point of departure. I did get a confirmation email for the cancellation request.
I've really no idea what is happening with it. I've never been asked to pay the redeposit fee for the miles. Then I got the impression from some of their more recent comms that I wouldn't need to pay for the redeposit of miles?
Lastly, just last week I entered my ticket number into manage my booking...that pulled up some flights, with a different PNR, same destinations but travel dates in about a years time. Will they ever get around to turning this into a miles / taxes refund...no idea!??
