There are a few rules to remember before you apply for this card. Most importantly, this is a small business credit card. You don't qualify unless you've got a business venture (which can be things like Uber driving or tutoring). Additionally, the card is subject to the Chase 5/24 rule: If you've opened five or more cards from any bank (excluding certain small-business cards) in the past 24 months, you're not eligible for the Southwest Rapid Rewards Premier Business Credit Card. You also won't be approved if you've currently got the card or if you've received its bonus within the past 24 months.
