In 2026, the way Southwest Companion Pass holders board has changed significantly due to the airline's transition to assigned seating, which fully rolled out for all flights departing on or after January 27, 2026. Under the new system, Southwest has replaced its traditional "A, B, C" open-boarding positions with a numbered group system (Groups 1–8). The good news for Companion Pass holders is that the companion now receives the same boarding group and seating benefits as the primary traveler. If the primary traveler has A-List Preferred status or purchased a "Choice Extra" fare (formerly Business Select), the companion will be assigned to the same high-priority boarding group (typically Group 1 or 2). This ensures that the two travelers can board and walk to their assigned seats together. However, it is important to note that because seats are now assigned at the time of booking or check-in, "sequential boarding" is no longer the chaotic scramble it once was; you will simply go to your specific reserved seats once your group is called.
