Sample Sale Fares
Please note, these fares are only available on Southwest.com. Other carriers regularly match these sale fares, so be sure to compare to find the best deal.
All fares also work in the reverse direction. These are the advertised sale fares. Some routes have lower fares than advertised.
Sale fares include a carry-on bag, a personal item, and two free checked bags up to 50lbs/23kg each.
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.
Searching Southwest's website, I found seats departing Boston BOS on Saturday, November 16, returning from Baltimore BWI on Tuesday, November 19, 2020, for $118 roundtrip.
