BA provided a solid business class product. It's seating arrangement is unique and I certainly appreciated the dreamliner. I probably won't go out of my way to use EWR just for the dreamliner anytime soon though. Only point of suggestion is that the arrival snack should see some enhancements. BA should look at what DL/AF/LX do on their Europe-US East flights.
