Talking to the call centre tells me that there are no award seats available for that date (Jan 19th), and to call closer to the departure date. What are the chances of award seats opening up then? (someone with experience?)
If you wait list on the flight and they have a seat spare they will normally upgrade you a few days before departure. If you don't have any Jet status then they will not upgrade you before hand until they are sure the seat will go empty which is normally 2-3 days before departure.
Your best bet is with vouchers as if the flight is quite full then they won't upgrade you with miles and when you check in that might be too late. If you wait list with vouchers then you have a chance to upgrade till the flight closes.
