In 2026, the most reliable way to get free priority boarding on Southwest is by achieving A-List or A-List Preferred status. Following Southwest's major transition to assigned seating in early 2026, the boarding process has changed: A-List members are now guaranteed a boarding slot no later than Group 5, while A-List Preferred members typically board in Groups 1 or 2. You can earn this status by flying 20 qualifying one-way flights or earning 35,000 tier-qualifying points in a calendar year. Another "free" method is by holding a Southwest Rapid Rewards Priority Credit Card, which offers four upgraded boardings (A1–A15) per year as a statement credit. Additionally, if you are an active-duty military member, you are often permitted to board between groups A and B at no extra cost. For everyone else, "priority" now relates to the seat you select at booking; however, the traditional "EarlyBird Check-In" remains a paid service rather than a free perk for standard ticket holders.
