Nah, the AC website just isnt very bright. The emirates segment on this books into O which is business lowest on EK but PY Flex on AC. The website gets confused and calls the itinerary premium economy even when its not. The fare rules identify it as a Business Excursion fare. This happens to me frequently whenever I do complex bookings through matrix but ticket through the AC site. Ive never had anyone actually try to treat the ticket any differently from what it really is.
