While Southwest Airlines didn't advertise its own sale this week, the airline has matched prices from sales on competing airlines like Delta and Alaska Airlines. Fares are as low as $78 roundtrip and include two free checked bags.

Travel Availability

Travel dates follow either the Alaska Airlines sale or the Delta Air Lines sale that we posted earlier this week.

  • Travel Period: August 14 - November 6, 2019. (some routes only August 20 - October 16)
  • Travel Days of the Week: Tuesdays, Wednesdays, and Saturdays for most routes.

Sale Period

These fares are unadvertised and may jump in price at any time. However, since the fares follow other airline sales, many of these fares will likely expire along with the Alaska Airlines sale tonight, June 13, 2019. The Delta sale expired yesterday, but we're still seeing these prices available today.

Baggage

These 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 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.

Alternate Fares

You may find similar or lower fares in these markets on other carriers, but all other airlines charge for checked bags—some even charge for carry-on bags. Southwest has the advantage of two free checked bags and no change fees.

Example Booking

Searching Southwest's website, I found a flight departing Chicago MDW on Saturday, September 7, with a return flight from San Francisco SFO on Tuesday, September 10, for $258 roundtrip.
