Promotion Code: 53093

The points earn on the new promotion vary a little from the old one. My question is around the points earn on one way tickets. The earning activities table says - Purchase a full-fare Economy Class ticket (Y or H) ticket to earn 6 points. Now, does that hold true for a one-way ticket? I have been buying all these one way Y class fares to double up on the earnings but want to make sure that they all count.
