Frontier Airlines is having another one of their $29/one-way sales. There seems to be good availability out of Atlanta. You might want to check to see if there is something good for you. Even if there is only a one-way availability, you could always book on points with a different airline the other way.
Make sure to use a card that will earn you bonus points on your airline purchase, like the American Express® Premier Rewards Gold Card which earns you 3X points for flights booked with airlines! You can read all about the additional new benefits of this card here, like the new $100 airline fee credit!
