Yes, you can cancel your Southwest Rapid Rewards credit card at any time, but you should be aware of how it affects your points. Under the 2026 terms and conditions, Rapid Rewards points do not expire as long as your account remains open; however, if you close your Southwest account entirely, the points are forfeited. If you simply cancel the credit card but keep your Rapid Rewards loyalty account active, your existing points remain safe and can still be used for flights. Crucially, any points you earned from spending will stay in your loyalty balance. However, you will lose card-specific perks like the annual "Anniversary Bonus" points, "EarlyBird Check-In" credits, and the ability to earn the Companion Pass through credit card spending. Before canceling, many savvy travelers consider "downgrading" to a no-annual-fee version to preserve their credit history.
