Delta has canceled the promotion on Nov 21st, but according to this internal memo,
"Customer who enrolled prior to cancellation may still earn bonus as noted"
So if you registered before Nov 21st, you should be able to get bonus as long as you complete activities by Dec 31st. bonus will be awarded 8-10 weeks after Dec 31st.
There is no way to confirm with Delta whether u have registered or not, if you did, u should get those bonus.
I am going to re initiate my SPG and Marriott transfers this weekend.
