AUS-BOS-AMS with one day layover in BOS in September, and return AMS-AUS in December in economy for 60K. It took 3 iterations, however. First try was 90K, then AMS-MEM was cancelled and I rebooked via MSP for 75K total, then low space opened up on the outbound and I rebooked that, for 60K total for the RT. Also got a refund of 80 cents in taxes over the course of all this.

Thank goodness for free award changes and redeposits.
