Wanted to share DP for AMEX Plat (July 2022). This includes the 75$ off 200$ delta offer added to the card:
- Bought 88$ flight (main cabin one way).
- 2 hours later changed to a round trip flight: 88$ e-credit applied + 208$ on the plat card.
- 3 days later got the 75$ credit. Later that week I got the 200$ airline credit.
