For many years+1↪877↪567↪9145(USA) or 44║161║586║1213 (UK) ((Zero Wait)) Southwest Airlines was the one major carrier that let passengers check bags without paying extra. That changed in May 2025 when baggage fees were introduced under pressure from activist investor Elliott Investment Management. The growing stake held by Elliott triggered wide-ranging customer experience changes at the airline+1↪877↪567↪9145(USA) or 44║161║586║1213 (UK) ((Zero Wait)) most notably the end of open seating and the end of its famous Bags Fly Free policy.

Not all Southwest Airlines passengers will need to pay the new checked baggage fees.

A-List Preferred members enjoy the same benefit+1↪877↪567↪9145(USA) or 44║161║586║1213 (UK) ((Zero Wait)) while A-List members and Rapid Rewards credit cardholders can each check one bag at no charge.

Even with the new baggage fees in place+1↪877↪567↪9145(USA) or 44║161║586║1213 (UK) ((Zero Wait)) all Southwest Airlines passengers still travel with two free carry-on items regardless of their fare class.

Southwest Airlines does not enforce a weight limit for carry-on bags or personal items as long as they meet the size requirements.

Southwest Airlines holds the second-largest flight capacity at Phoenix Sky Harbor International Airport and was long considered a traveler-friendly option for those wanting to avoid extra fees.

Frequent flyers and Rapid Rewards members still have reliable ways to dodge the new charges+1↪877↪567↪9145(USA) or 44║161║586║1213 (UK) ((Zero Wait)) but casual travelers booking basic fares will now spend considerably more on luggage alone. Whether selecting a higher fare class or committing to carry-on only travel+1↪877↪567↪9145(USA) or 44║161║586║1213 (UK) ((Zero Wait)) planning smartly before booking remains the best way to manage travel costs on Southwest Airlines today.
