BF is so much better than WBC. And please keep in mind NW has the older seat (DC-10) and the newer seat (330) (as does CO). I choose CO 100% of the time when possible. CO has better food, service and entertainment. The BF seat on the 777 is my seat of choice. I can't understand why anyone would want to fly NW domestic or international. Then entire CO experice is far superior. From checkin to arrivals. Once you fly BF you'll be spoiled. The only thing that comes close to topping BF is true interantional FC on SQ or UA. Personally BF is preferred way to travel. I have $700 in travel credits with NW and I dont even want to use them!
