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 Atlanta ATL on Thursday, March 12, returning from Pittsburgh PIT on Monday, March 16, for $166 roundtrip.
