Yes, you can earn a Southwest Rapid Rewards credit card sign-up bonus again in 2026, but you must adhere to Chase’s "24-month rule." Specifically, you are eligible for a new cardmember bonus if you do not currently have that specific Southwest card and it has been at least 24 months since you last received a new cardmember bonus for that same card. This rule applies separately to the Personal cards and the Business cards. For example, if you earned a bonus on a Plus card in 2023, you can apply for a Priority card in 2026 and get the bonus. Additionally, you must be under the "5/24" limit, meaning you haven't opened five or more personal credit cards from any bank in the last 24 months. For 2026 travelers aiming for the Companion Pass, timing your application for early in the year is the most effective way to maximize the value of these recurring bonus opportunities.
