It's classed as a league fixture so included i would assume. The final however, as its at a neutral ground (Wembley), i would take a guess that those tickets have to be purchased at an extra cost.
You will have the option to keep your st seat but will have to pay either saturday prices or tuesday night football prices depending which day is our home game, playoff home game isn't included because we arnt defo there at the start of the season so the cost doesn't include this one extra home game
