worked well here...
Hi All,
Received the Signature Visa 50,000 bonus miles offer 4/15 afternoon via email. After browsing the posts on FT over the weekend, I submitted an application via email 4/19 and got an email response saying I would be contacted by (snail) mail. Next came a text alert from my credit monitoring service which turned out to be an inquiry by Chase through Experian. On 4/20 I called the Chase back number (thanks much for the info everyone), put in my SS# and the recording confirmed approval wth a handsome credit line. Card arrived today. Making large purchase tomorrow so I should know about the time frame for 50,000 miles posting in the near future.
