In general I discovered that this who have frequent traveller silver and up can buy premium economy on that route because premium economy class and frequent traveler silver are complementary to whole business class.
-business class check-in
-business class security
-seat with business class( only difference that seat next to you can be occupied)
-food and drinks these same as business
-baggage- 2 x 23 kg as frequent traveller also(business 2x 32 kg)
In general I had two seats for myself so I can tell that I has a business class in price of premium economy.
It was very comfortable flight
