There are several common reasons why a Southwest Rapid Rewards account might be disabled in 2026. The most frequent cause is prolonged inactivity; if you do not earn or redeem points within a 24-month period, the account may be deactivated, though Southwest points themselves no longer expire. Another common reason is a security flag, which happens if there are multiple failed login attempts or if the system detects suspicious activity, such as your account being accessed from an unusual location. Southwest also disables accounts if they suspect a violation of their "Terms and Conditions," specifically regarding the unauthorized sale or "brokering" of points or companion passes. If you are part of a corporate travel program, your account might be linked to your employment status. To resolve this, you generally cannot fix it through the app; you must call the Southwest Rapid Rewards customer service line directly. They will verify your identity and, in most cases involving simple security locks or inactivity, they can reactivate the account and restore your points balance immediately.
