The Southwest Priority Lane (and the similar Express Lane) is a dedicated service designed to speed up the airport experience for the airline's most frequent and high-value travelers. Specifically, the Priority Lane is located at the Southwest check-in counters and is available to A-List and A-List Preferred members, as well as those traveling on Business Select fares. This allows these passengers to bypass the standard line for baggage drop and ticketing. The Express Lane is the equivalent at security checkpoints in participating airports, providing a faster route to the TSA screening area. In 2026, these lanes are a key perk for business travelers who value time-efficiency. It is important to distinguish this from Priority Boarding, which is a separate paid upgrade (purchasable 24 hours before flight) that grants an earlier boarding position in the A1–A15 group to ensure early access to overhead bins.
