Seat Assignments
Southwest has an open seating policy, which means there are no assigned seats, and you'll get to choose your place 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 El Paso ELP on Thursday, February 6, returning from Phoenix PHX on Monday, February 10, 2020, for $138 roundtrip.
