I just did this as well and was approved just 2 minutes ago
"I just followed the instructions of post #184, credit card agent asked if I was applying for the 50,000 miles Visa, then he took my application and I was instantly approved. Overall, it took about 15 minutes."
I entered in wrong zip code, was transferred to an agent, asked for the 50,000 visa offer and they took my application right away.
