Travel is available Monday through Thursday and Saturdays from late August through the early November. Summer travel dates scarce, but there are a few select dates in June available.
Searching Southwest, I found this price available departing Boston BOS on Thursday, September 5, returning from Austin AUS on Monday, September 9, 2019.
This fare includes a carry-on bag, a personal item, and two free checked bags.
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.
JetBlue and Delta are matching this $207 roundtrip fare, but inventory is limited on select dates. If you are having trouble finding travel days that work for your schedule, try booking two separate one-way tickets amongst the airlines and create a custom itinerary.
See our fare details for booking info.
