An economy class (Y class) private suite includes a continuous seatback and a stowable aisle-side panel. The continuous seatback covers the gaps between seats of a 3-seat or 4-seat PAX and the stowable aisle-side panel slides to close off the PAX from the aisle when desirable. Each seat in the PAX includes an extension element to extend from the anterior surface of the seat cushion and establish a substantially flat surface including the seat cushions and extension elements. A separate padded element may be placed over the substantially flat surface. Each seatback cushion in the PAX is removable and reconfigurable as a reclining support or expanded armrest.
