I have never travelled economy on EVA and it has always been PE and one time Business class. I thought the business was much better than QR and CX that I have flown long haul recently. Apart from the boarding procedures that they have. I have one coming up pretty soon in end June or early July and to me the down side of PE is that it is always full. I have never seen a half empty cabin in PE and the most I have seen is about 3 seats empty.
