The 10% up to $40 off with $25 minimum spend is showing up across all my Chase credit cards (non-SWA ones), so it might be a wide desperate push. They sometimes exclude people who already have used it or has a Southwest charge recently.
It expires at end of month and is for travel in May or June only. If you use it for later travel, only 5%. Obviously, you would want to book before late May to obtain WGA fare benefits.
It is crazy that the Chase Offer is promoting 2 free bags still.
I know others have used the Bank of Southwest via warehouse gift cards, but I don't like large gift cards in general.
