A few 12 months in the past, Southwest introduced the primary of many operational adjustments. The primary blow was the top of open seating, which the airline introduced final September and can go into impact in January 2026.

Southwest’s new baggage price

Previous to this transformation, Southwest flyers might examine two baggage freed from cost. For bookings made Could 28 onward, Southwest now expenses $35 for the primary checked bag and $45 for the second.
