How can I select a seat with Southwest Airlines?

Open your Southwest Airlines booking and check the seat map for each flight. Whether you can choose a seat for free, pay for one or receive an assignment later depends on your fare, flight and available seats.

The telephone options below are for new bookings, flight changes or cancellations only. They are not baggage-claim, loyalty-account or refund-status support.

What this answer depends on

  • Southwest uses assigned seating for travel from January 27, 2026, with seat-selection timing and included seat types depending on fare and traveler benefits.
  • Most fares can select a seat during booking, while Basic generally receives an assignment at check-in unless an eligible status or card benefit applies.
  • If no seat is selected, Southwest says it will assign one at check-in or at the gate, subject to availability and its family-seating process.

Important unknowns

  • Exact travel date
  • Fare bundle
  • Rapid Rewards tier or eligible card benefit
