Potentially interesting DP:
9/22 - Selected Southwest as Airline for Amex Plat benefit. Minutes later received email.
9/22 - Minutes after email, purchased in two separate transactions two one-way tickets on Southwest.com totaling 196.48
9/24 - Charges go from pending to posted
9/25 - Meter moves, showing I have $3.52 left
9/26 - Credits totaling 196.48 post to my account. Additionally, I purchase a total of 8 one way tickets on Southwest for upcoming trip using my Amex Plat. None of them are under $108. I did use travel funds from previously purchased tickets (on 9/22) to cover some of the costs of two of the tickets...
9/28 - Those purchases go from pending to posted, and meter now shows I've used all my credits
9/30 - Credit for 3.52 posts to my account.
Weird... I don't understand the $3.52 unless by using the travel funds from the other tickets brought down the cost of the new ticket enough to trigger the Amex credit. Whatever it was, I'll take the remaining $3.52 that I thought was lost.
