14 Airline Credit Cards That Offer Free Checked Bags in 2026

4. Southwest Rapid Rewards Priority Credit Card - Unlimited Companion Benefits

The Southwest Rapid Rewards Priority Credit Card stands out in 2026 as one of the most family-friendly airline credit cards available, offering two free checked bags for the cardholder and up to eight companions on the same reservation, creating exceptional value for group travel scenarios. This card's annual fee of $149 is quickly offset by its comprehensive benefit package that includes 7,500 anniversary points, effectively reducing the net annual cost while providing ongoing value. The card's earning structure is particularly robust, providing 3X points on Southwest purchases, 2X points on local transit and commuting, internet, cable, phone services, and select streaming services, plus 1X point on all other purchases. Southwest's unique approach to customer service and operational reliability makes this card particularly appealing for domestic travelers who value flexibility and customer-friendly policies. The card includes four upgraded boardings per year, which can be valuable on Southwest's open seating flights, and a $75 Southwest annual travel credit that can be used toward flights, Early Bird Check-In, upgraded boardings, or in-flight purchases. The welcome bonus of 70,000 points after spending $5,000 in the first three months provides substantial value for new cardholders, particularly given Southwest's extensive domestic route network and reputation for operational excellence.
