"Extend your new A-List for 12 months by booking and flying three round trip revenue flights (or six one-way revenue flights) within 90 days of today." That was on the email confirm of my current status match request. With WN, I never book round trips and have always booked one way segments, but I would have assumed the wording had meant that a combination of round trips and one ways would've fulfilled the requirements of the match, not literally either 3 RTs *OR* 6 one ways.
