I have searched both Delta and Air France forums, but still need some specific input from any of the more experienced folks out there.

Just booked a trip to Italy in November via Delta's website.

Return leg is on Air France from CDG-LAX on 11/30/12 departing CDG at 1:15pm.

I booked into Premium Economy, have 1 seat in Row 18, 1 seat in Row 20 for my wife and I (the only seats that were available when I booked).

Delta Itinerary lists the equipment as an Airbus A380-800 for Delta 8395 (AF66).

When I check the flight on Air France, it lists the equipment as a Boeing 777-300 (303 seats configuration is the one that matches the seating arrangement Delta presents on it's site for seat selection).

My questions are:
1) Which equipment am I really flying on?
2) What do you think my chances are that seats will free up and I will be able to change seat selection so my wife and I can sit together.
3) Despite being Delta PLAT, with plenty of miles and SWUs to use for upgrading, likely the recent Air France actions to block Delta upgrades will likely prevent me from moving up to Business - right?

Thanks!
