I found business saver space for my wife and I on our red-eye return flight PPT-MSP (mixed fare with domestic leg booked in XN class). They've offered to put me on a wait list for IN class on our outbound long-haul leg. Think I'll pull the trigger and let them deduct the points now... I've been checking every day and there's occasionally saver award space (which is what we're currently booked in), but haven't seen business saver available the past few months. Anyone have any experience with being on this sort of waitlist? There's currently about 43/48 Polaris seats available from what I can tell.
