We just did a DTW-AMS return a couple of weeks ago - on the A350, the suites are a joke compared to QR
But as we say, anything is better than true economy and the GUCs came through at 24h (pushing us from Premium select at booking to Delta One by flight time)
For a 900$ r/t economy to go in Delta One it was not a bad deal.
Yeah, I don't expect D1 to be QR - but as you said definitely better than coach and PE.
i get the DTW-AMS 24-hour to D1 from coach - but did you also get D1 from coach AMS-DTW? Was it automatic?
