Purchased mid-May: 134K SkyMiles X 4 MCI-ATL-AMS-DTW-MCI for August (purchasing PremiumSelect with confirmed suites on A359 on transatlantic flights using 8 GUCs for early August. Actually going to BGO, but no award tix AMS-BGO available at booking (very odd--can pay cash all the way through to BGO, but couldn't book cash or miles tix via DL for AMS-BGO legs). A few weeks later, could book (via DL app only; not via DL website) 4 X AMS-BGO and BGO-AMS in J at 25K Skymiles/flight)--so per person, it was 134K RT miles (plus 2 GUCs) to AMS in J, then another 50K Skymiles per person roundtrip AMS-BGO. No Y awards available on DL app; only J for AMS-BGO legs, but Flying Blue wanted 75K per leg in Y (don't really care about J for the 90 minute flight in Euro"Business" but was only option other than using FlyingBlue points to pay triple price in miles for Y). And not horrible redemption compared to $10K/ticket cash option....
