We booked this flight because it offered us free cancellations, checked bags and extra leg room. (Leg room because one of us has an artificial knee and is far more comfortable with extra leg room.) We had planned to fly Delta, but to get those conditions met, it was far too much money. So, we tried Norwegian Air, first class. (And, we never fly first class.) But, it offered us those conditions. It was great. Everything went flawlessly. We slept, had good food and arrived less jet lagged than normal.
