How many discs exactly are included in Microsoft's flight simulator X Gold Edition? - flight simulator x

I bought the game today, save in a game and I think he only had the flight simulator deluxe edition, not the expansion pack acceleration. Ithink it should have been two cases of DVDs in the package with 3 or more disks. I have identified only 1 box with 2 DVDs in both Flight Simulator X Deluxe Edition Disc 1 and 2. He did not receive the activation code of the product.
