All Nippon Airways Mileage Club - NRT-PVG Question

I will be flying NH921 from NRT to PVG tomorrow.

About 2 weeks ago, the aircraft on the seat map was changed from a 772 to the new 77W.

Could anyone who flew this route recently confirm whether the new 77W is indeed the aircraft being used?

Thanks

Yes I can confirm.
It'll definitely be confirmed if you check in online.

Yes, and they had the new staggered biz.
