The easiest airline credit cards to get approved for are those available to people with good credit that also charge annual fees, such as the Southwest Rapid Rewards® Plus Credit Card.

The Southwest Rapid Rewards® Plus Credit Card is generally considered the easiest of the Southwest personal cards to get approved for. While all Southwest cards are issued by Chase and typically require a "Good" to "Excellent" credit score (usually a FICO score of 670 or higher), the Plus card is the entry-level version with the lowest annual fee ($69). Because it has the fewest premium travel perks compared to the Premier or Priority versions, it sometimes has slightly more flexible internal underwriting, though the core credit requirements remain similar across the family of cards. It is important to be aware of the Chase "5/24" rule, which means you likely won't be approved if you have opened five or more credit cards from any issuer in the past 24 months, regardless of how high your credit score may be.
