Ask if there is any upgrade seat available on the flight and date that you want to travel. If there is, ask the agent to book the flight in Y or M and do the upgrade at the same time. You need to issue the ticket right away though. You are not allowed to "hold" the reservation without issuing the ticket.
I will give this a try.
My friend has SSWU, does it work the same way if he book the cheap fare? or is it better to pay the y/m fare and get guarantee upgrade?
