I logged into my Southwest Rapid Rewards account today to find an interesting and somewhat cryptic Promotion available for registration. While this is not confirmed, it looks like all flights in or out of Southwest California, Denver, and Atlanta will be receiving double points and double TQ points. The details and date range have not been loaded yet but I could register successfully. The message is below.
For most Southwest promotions, you must book (or rebook) your flights after you have registered for the promotion. They do not give you promotion credit retroactively.
