I applied late Wednesday night for the 25,000 after $1,000 spend offer and got the application pending. Called them Thursday and spoke with a representative and she was able to approve my application (even being at like...12 hard inquiries now and 8 new credit cards in last 3 months)!
I already have 3 AMEX cards (1 Delta, 2 Jetblue), so I sent a SM to Membership Rewards points noting the last 5 digits of the card and reference # in my approval email and the offer code for the 75k points. They said the same thing that most of you got - the 25k would post 6-8 weeks after $1k spend, and to message back for the 50k points.
FANTASTIC CUSTOMER SERVICE!!! Very nice agent, and I love this company!
