I'm not so sure about the killing the A330 and A340 thing. The A330 has less range than the A350, so it seems logical that if you want to only operate transatlantic, then the A350 is too much aircraft (I'm assuming it'll have a higher take-off weight than the A330 to get that range). I can see the case where the A330 and the A350 are operated together especially if Airbus works their magic and gets a same type rating for the crews. Look at Northwest - A330 on Atlantic, A350 on Pacific. perfect!
