So I applied for, in order.
1. Delta AMEX Biz card, 30K after 500spend, via telephone
2. Chase United Explorer, 50K after first use, via online
3. Chase Southwest Business 50K, via online

And ALL THREE were placed upon further review.. ...... I have a 780 score, and haven't applied for any card since last May !!!!!!

Ok, I am quite annoyed I didn't get a single one approved.
