Jetblue lost interest in the badges
I'm glad you brought this up bc it seems like I hadn't earned a badge in a while despite taking many flights also little thins like the "eat your cake and fly" birthday month badge which earns 500 points and 6 mint flights which earns 500, when badges stopped counting mine at 5. I feel so petty when I call to inquire but then I remind myself that it denied me mosaic for being 100 points shy of the 15k a couple years ago so the airline doesn't care, it wants be accurate.
I get the sense JB is sick of it and should just disband the program or make it work properly.
