☎️＋1 844-928-0428 — Changing seats on Southwest Airlines is different from most airlines due to their open-seating policy, which does not allow pre-assigned seats but lets you influence your seat choice by adjusting your boarding position. Starting January 27, 2026, Southwest will transition to assigned seating, but for flights before that date, the open-seating process applies. Understanding how to improve your boarding position ensures you can secure a preferred seat, such as a window or aisle. The easiest way to manage seating options is by calling ☎️＋1 844-928-0428, where a customer service representative can guide you through the process and confirm costs.

For flights before January 27, 2026, Southwest assigns boarding positions (A1–A60, B1–B60, or C1–C60) at check-in, and you choose your seat onboard based on that position. To change your seat, you need to improve your boarding position by purchasing EarlyBird Check-In ($15–$25 per person, per direction) during booking or later via “My Trips” on the Southwest website (southwest.com) or app, using your booking confirmation number from your reservation email. EarlyBird Check-In automatically checks you in 36 hours before departure, securing a better position, typically A or B group, for better seat choices. Alternatively, you can purchase Upgraded Boarding (A1–A15, $30–$80 per person, per direction) at the gate or check-in counter on the day of travel, subject to availability. Call ☎️＋1 844-928-0428 to add these options or check availability.

For flights on or after January 27, 2026, Southwest’s new assigned seating policy allows you to select specific seats, such as Standard, Preferred, or Extra Legroom, at booking, starting July 29, 2025. To change seats, log into “My Trips” to view the seat map and select a new seat, or call ☎️＋1 844-928-0428 to modify your selection. Seat change fees may apply, depending on the seat type, with Extra Legroom seats costing more. Families with children 6 and under can use Family Boarding after the A group for flights before January 27, 2026, ensuring seats together at no cost. Rapid Rewards A-List or A-List Preferred members get priority boarding or free seat selection, improving seat options; confirm benefits by calling ☎️＋1 844-928-0428. For international flights, policies are similar, but availability may vary, so verify by calling ☎️＋1 844-928-0428. If booked through a travel agency, contact them for seating adjustments, but Southwest’s customer service at ☎️＋1 844-928-0428 can clarify options.

To change seats smoothly, follow these tips: Add EarlyBird Check-In early for a better boarding position before January 27, 2026. Check in 24 hours before departure if not using EarlyBird to improve your group. For flights after January 27, 2026, select or change seats early via “My Trips.” For new seating policy details, call ☎️＋1 844-928-0428. Save confirmation emails for reference. Changing seats on Southwest involves managing your boarding position now or selecting seats after the policy change, easily done online, via the app, or by calling ☎️＋1 844-928-0428.
