I had a Barclays AA card that I got last October 2019. I didn't put much spending on it. (I know, mistake.) I am thinking of going for the Barclays Jetblue card with 100k points offer within the next two weeks. Question: What will give me a better chance of approval for Jetblue card? Should I close Barclays AA first or just apply for Jetblue card, or try to put some spending now on the AA card (not sure if it will still help)?

Thank you.
