Here is my return trip (I haven't bought ticket, but this is the fare basis for the ticket i will buy probably next week, it may change, but this is it as of now)

F fare - selected from the right hand column on the website (First class (Lowest))

So, it is an "E" fare, with up to F - Without looking at fare basis, you would never know this.
