Bough 2x100 TB using my platinum card on the 12/19 right after receiving the confirmation of airline change, no credit posted yet.

Bought 2x100 and 1x50 TB with my Aspire card 24 hours after airline change on 12/23, all credits showed up this morning with posted date of 1/1/2024.

Maybe time between loading TB and airline change affect speed of posting?
