Plane was clean and nice. Crew was very nice. Price was excellent. That said, for the discount price, you don't get food or drink except for water, coffee or tea. As with most carriers today, you must also bring your own entertainment, or at least your own headphones that plug-in - bluetooth will not do. So keeping the price in mind, I think it is a good value.
