Yes! All of us at MMS collect Southwest points. Southwest is the most customer-friendly airline in existence. Their cheap fares are easy to locate with the Southwest Low Fare Calendar. Our readers love Southwest not just because of their genuine staff, but because you’ll get two free checked bags and free changes/cancellations up to 10 minutes before takeoff. In other words, you could be sitting on the plane and decide you don’t want to fly, and Southwest will give you your points back free of charge.
