Ril Jaa follow these steps and you will locate the reward. Login to e-Rewards and at the top click on "Rewards" and then click on Southwest,

I did this recently with an AA bonus. So once you get to the reward redemption page for Southwest the very first reward should be for 0.00 dollars. I don't remember exactly how the page looked. But this 0.00 dollar award does not carry the normal e-Rewards restrictions like not being able to redeem from the same company within 90 days. You can redeem with Southwest again tomorrow if you have enough money to redeem.

Anyway that is how it works. If there is no 0.00 reward to redeem I don't know what to tell you. It has happened for me with AA, and others I know have done it for AA and AS.
