Be sure to check your SkyMiles earnings after your flight, especially if your new VS flight number has retained the G fare, which is not a VS fare. When I had problems with mileage credit for the VS flight I found the best way to correct it was through an email via the Comment/Complaints option on delta.com. Phone calls were not effective.
Thanks for the advice.
I recall the AF upgrade deal, but their PE fares seem to be considerably more expensive than VS ones. There's also the misfortune of having to fly on AF in the first place
