New to using Amex plat with DL as my airline fee credit option (previously did AS and UA but now DL is my most used airline). What's the best way to follow this gift card/ecredit process if I have multiple amex plat fee credits to use? Do i need to buy a gift card for each one or can the first ecredit be "recycled" into buying a more expensive ticket for fee credit #2 and then again for #3? I think this might be similar to what user diesteldorf mentioned a few posts before me but not positive.
Hypothetical steps:
1 - buy $50 DL gift card
2 - purchase ~$250 flight with $50 GC and ~$200 remaining charge on Amex Plat #1
3 - cancel flight from step 2 for ecredit of ~$250
4 - purchase ~$450 flight using the ~$250 ecredit from above and then remaining ~$200 on Amex Plat #2
5 - cancel flight from step 4 for new ecredit of ~$450
6 - purchase ~$650 flight using the ~$450 ecredit from above and then remaining ~$200 on Amex Plat #3
7 - cancel flight from step 6 for final ecredit of ~$650
