To share my experience, I applied exactly at 12:00:00 AM Doha time, got the notification message and then 3 days later I got the promo code. Was unable to find any flights to Male/Maldives like I wanted, but we booked Boston to Singapore for around $75 each. I tried to upgrade to business but got an error message, so obviously can't do a rewards upgrade but hoping we can do it for cash at checkin.
