Please excuse the newbie question, but just wanted to check before I purchase.

If I price out the same premium economy itinerary on virgin atlantic and delta.com, for a VS operated flight, I get quoted a cheaper fare by abour $1000 booking via delta. The fare class is W and it shows under Delta Comfort+, but I know C+ isn't really a true PE cabin where on VS it is.

So if I book via DL at this fare, I'll still get into VS's PE cabin?

Thanks.
