Delta had made many Delta One seats available on these ex-SEA routes when they were scheduled with the far less preferable 767-300's. They seem to have swapped the new plane in but left the copious award space, at least initially. I scored awards for SEA-PVG for 5 in Delta One, using VS miles, but that meant there were at least 5 low level D1 awards. There are still more showing on my date of travel. For some dates I was seeing 6 and 7 D1 awards available. For us it's a real win as we had CX awards out of YVR and would rather not drive up there and instead fly out of our home airport on a pretty much brand new plane. If you have AMEX MRs, it's only 60k plus a few bucks in taxes. We had moved a ton of MRs over during the last MR to VS promo so these awards have an effective cost of under 50k MRs per ticket. Strong redemption value for one of the best J products in the sky.
