I have a flight scheduled in mid april iad/lhr. It was originally on the 777 with no f. We are in club world. Just checked the reservation and discovered we are now on the new A350-1000. They have assigned us seats 15 d&e. From what I can tell it is in the mini cabin in the rear. I equate them to the ud on the 747. Is this a valid assumption or are there better seats in the main business cabin?
