It added several benefits on top of the Wanna Get Away fares, including free standby, free same day confirmed changes, more points per dollar spent, and the ability to transfer flight credit to other people.
But one unexpected benefit is that if you have Southwest flight credit that is tied to one person from a cancelled Wanna Get Away ticket, you can use it to book a Wanna Get Away Plus fare and then cancel that Wanna Get Away Plus ticket. You will then be able to transfer those funds to any Southwest Rapid Rewards member.
If you book a ticket that costs more than the value of the flight credit and cancel within 24 hours you’ll get a cash refund for the amount above the value of the flight credit and a flexible flight credit for the amount of the original flight credit.
Alas, the expiration date of the funds remains the same.
As with free flight changes with no difference in fare, Southwest may eventually close this workaround, so enjoy it while it lasts!
Of course when you use Southwest points (transferrable from Chase) you can always cancel for a refund, so there’s no need for this workaround and there’s less of a reason to buy up to a Wanna Get Away Plus fare.
It’s also worth noting that Southwest tickets under $109 count towards AMEX airline fee reimbursement. With this method those funds are now more flexible.
