Hi everyone, here's my time line:
Sometime around the end of September: I changed my preferred airline from Hawaiian airlines to Southwest (American Express allowed it because I didn't use the credit this year; I called and made this request).
October 4 2022 - transactions were as follows: $76.20+$56.20+$38.10+$28.10=$198.60 (2 one way tickets, 2 one way tickets, 1 one way ticket, 1 one way ticket=total of 4 reservations but for 6 tickets)
October 7 2022 - the tracking meter reflected the credit was used, said $199 was used. Surprised that it reflected this on a Saturday.
October 8 2022 - credited by American Express as follows: $38.10+$38.10+$38.10+$28.10+$28.10+$28.10. Surprised that this credited on a Sunday.
