Punxsutawney Phil popped up to say that spring is in the air early this year, and you should be too! Hop to destinations all across America this spring with Southwest's newest 3-day sale featuring fares as low as $39 one-way on Interisland Hawaii flights and continental travel starting from $54 one-way or $108 roundtrip.

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 San Jose SJC on Tuesday, March 10, returning from Las Vegas LAS on Saturday, March 13, 2020, for $108 roundtrip.
