It’s back, and this week’s deals extend travel dates to Hawaii through early November. Travel dates for discounted fares are as follows:Within the continental US: August 20 – August 29, and September 3 – October 30, 2019.Hawaii inter-island: May 28 – November 2, 2019.To/from San Juan, Puerto Rico (SJU): September 4 – October 31, 2019.International routes: August 20 – October 30, 2019.In order to qualify for these discounts, your trip must be booked by May 9, 2019. As always, Rapid Reward award redemption bookings do not include government fees from $5.60 per one-way flight.All fares are nonrefundable, although Southwest does allow you to convert nonrefundable travel credit toward a future flight within one year of the original purchase date. And if you’ve already made a reservation through Southwest and later find that the price of the ticket has decreased, you can request the difference in fare with no change fees. Also remember that Southwest award redemptions are tied to the ticket’s price, so this is a prime opportunity to use Southwest miles for a cheap trip.
