Elevated Delta Offers expiring SOON (available via certain support links).
I am not an expert on these offers so if anybody else wants to chime in, please do so.
All of the Delta cards have elevated offers available ONLY through support links and then expire on 5/1/19! I'll list each offer below and then list who I found on the AMEX support thread that has links

I would always advise consulting here before you actually apply in case somebody feels you're making a bad move.
DELTA GOLD PERSONAL: Earn 60,000 bonus miles after you spend $2,000 in your first 3 months and a $50 statement credit after you make a Delta purchase within your first 3 months.

EDIT: If anybody else updates their links to the elevated offers, let me know and I can add your name here. A lot of others have Delta links but they aren't for these higher offers.
EDIT2: You might be able to do a support link via spouse or self-support here as well. Please read my next post about a warning on self-support though.
