Gustav,
When I click on the link on the main page it leads to another page that leads to this page
https://wwwa.applyonlinenow.com/USCC...ntry?sc=UAAECS Apply here. You'll get 25,000 miles (20K base plus 5K for the spend), with the Signature card, when your charges reach $750. If your credit is good & your income is sufficient, you "should" be approved the Signature card. YMMV of course.
