Same story here, trying to get from PE (N) to C on LAX-ZRH about 3 weeks out, quite some inventory open + cash upgrades and bids are still open...
Let's see when the waitlist spot will materialize.

Question - If I keep on bugging M&M every few days is there a way for them to push it through the waitlist? Any tips & tricks or the system will only open it up few days to few hours from departure?
