Mopti - The last time I flew to Lima on a BF configured plane (a couple of years ago), there was no 30 day out limit on mileage upgrades, and I don't think that has changed.
I think that you can still confirm your UG at the time of purchase for South America routes with BF service if there are Z class seats showing.
Somebody please correct me if I'm wrong about this.
