A LoyaltyLobby reader sent me an email earlier today with a screenshot of Wyndham Rewards website stating that the partnership was ending effective August 31, 2015.
And that indeed seems to be the case. When you log into your account and have a look at the airline partner options, there is a note in red about this change.
You can check the Wyndham Rewards airline partner earnings here.

I would assume that Wyndham and Southwest Airlines have not reached commercially viable agreement that would satisfy both parties. Considering the Wyndham portfolio of hotels (midscale to budget/economy), the audience is a perfect fit with Southwest.
Sometimes when these partnerships end they are resurrected couple of years down the road (what happened with Marriott Rewards and American Airlines).
