Bought 2x100 for my Schwab platinum right after receiving the airline change confirmation on 12/19, no credit yet and meter has not moved.

First time doing this and I honestly don’t care if it takes a month to post for this card, but I have another vanilla platinum that I need to cancel before the end of 1/14/2024 to get my annual fees back (no retention offer after 13 months since I got my last one) and I’m debating if I should risk purchasing TB tomorrow as I’m not sure if the credit would be posting before 1/14…

My main airport is DFW so we don’t have much of a UA presence here, really debating if I should take the risk…
