Seat Assignments

Southwest has an open seating policy, which means there are no assigned seats and you'll get to choose your seat during boarding. The order of boarding is determined by the time of check-in, so check-in exactly 24 hours before departure or pay for priority boarding for a better choice of seat.

Example Booking

Searching Southwest's website, I found seats departing San Diego SAN on Wednesday, September 25, with a return flight from Sacramento SMF on Saturday, September 28, 2019, for $98 roundtrip.
