I am thinking about applying for the Business AAdvantage, but had a couple of questions. I have a small side business (established in 2006, not much income, nothing in the business name, no checking account). Should I apply with my EIN or SS? Is Citi easier to deal with than Chase for a business card? I was able to apply for an Ink card with my EIN, but I spent about 20 minutes on the phone with Recon answering questions about my business.

Ultimately, I would like to apply with my EIN to establish credit under the business name, but if it is going to be a hassle, I will use my SS.

Thanks!
