Just an update: Finally got a phone call from B6 and thanked me for considering JetBlue. Agent congratulated me on being Mosaic 4. I asked her about the BLADE certs and the Mint certs. As for BLADE, codes will be sent via welcome email. She did say that if I haven’t received the email but want to make a booking, they can manually add a promo code. In terms of Mint certs, they’ll be replenished again in 2024 once status has been renewed.
