SWA - How do I apply my travel funds?
 

I see where to view the travel funds I have accumulated but how do I apply them?

when you book a trip, a box is available for you to enter in the travel funds numbers you want to use before it calculates the bottom line you may owe by credit card.

Thanks!

Note they seemed to have changed the website recently that you have to click to drop down a menu to fill it in. So not necessarily obvious on the payment page. But it's there.
