Baggage

Sale fares include a carry-on bag, a personal item, and two free checked bags up to 50lbs/23kg each.

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 Ontario ONT on Saturday, November 16, returning from San Francisco SFO on Tuesday, November 19, 2019, for $108 roundtrip.
