However, you are right about Business Class Discount 'P' fare.
A few other Star Alliance carriers also have premium economy products, all Air Canada PE buckets earn 130% miles, Air NZ an excellent product. Have not tried any other carriers PE but have noted a few earn no miles (ANA discounted PE). Wish TK would bring back Comfort Class, it was an excellent PE product.
