I put in a bid for 220euro for MXP-JFK and was accepted, although I didnt get an email regarding my offer being accepted, only come to find out during check in that my bp showed Business instead of PE.
As this was all booked through AZ(055 ticket number) and crediting to DL to get the dollar qualification value, Z class for successful upgrade bid doesnt earn anything according to DL chart, I was originally booked in A class, so question will be what will AZ provide to DL as to how my mileage earnings will be?
