Thanks for the summary, OP, very helpful. The ways of the Robot (and indeed the whole system) are indeed mysterious. Quick question in case anybody knows - Elite booked LAX-AKL for 10 days time on a night with 2 flights, and 16 22 BP seats available on one of the leased aircraft (3 class). Booked Econ on this flight., using 2 x RU to upgrade. I’ve been offered a decent fare to UG to PE (and then lodge a single class UG). Question is - how does the Robot see a single vs double cabin Elite UG? Do I stand a better chance from PE to business? As a data point for others - I booked AKL-LAX last minute on Boxing Day 4 hrs out from travel PE to business. Confirmed on checkin. NZ aircraft with 20 seats free. Lodged via Robot.
