Hi. I have six Southwest credits that will start to expire this Dec. I want to try to earn the 12,000 points I will need to keep them and this will most likely be without flying. I don't know if this is doable at all or not. I just signed up for their dining program, so will use that. It seems like they don't have the surveys and shopping sites like United and American, unless I'm missing something. Any other ideas of how to rack up some non-flight points? TIA!
