I have recently redeemed my first international premium cabin on a Delta RT flight from IND-PVG. As I had time constraint to get in/out of the country, I did not utilize any possible stopover/open-jaw. The cost of redemption was for 140k from IND-JFK-NRT-PVG-DTW-IND. Now that I've redeemed it, I'm wondering if it was worth it? Seeing the blogger Lucky utilizing 90k US Airway miles on such an extended trip adds to that... doubt.
