In order to purchase miles I went to the following webpage:
https://www.flyingblue.aw/en/move/login
Then when I click log in I get the following error message: {"error":"invalid_request", "error_description":"It is not possible to log in right now. Please contact Flying Blue customer service for assistance. Mention the type of error: "Redirect URI does not match", so we can help you as quickly as possible."}
Does anybody know a workaround to purchase miles?
