The Interstate Lounge EXT seats up to nine and is perfect for travelers in search of versatility and space. It offers tremendous flexibility, room to socialize, and sleeping accommodations that will make you feel right at home. If you’re looking for a large galley area, open floor space, and easy access to storage, you’ll find it in the Lounge EXT.

Compared to the Interstate Lounge, the EXT offers an additional 30 cubic feet of storage and also includes a rear power sofa that converts into a larger bed, 6 feet 10 inches in length. All Lounge EXT series floor plans have an optional seat in the rear lounge area in place of the overhead wardrobe.
