Southwest periodically make flights for further in the future available. They’ve added flights until August 14th, 2017 (previously the schedule was only extended until June 2nd). Southwest has a generous refund policy and their flights are typically cheapest when the schedule is first released, so if you have travel plans involved Southwest I’d suggest booking now (worst case scenario you can cancel/rebook or just use the change flight button to receive a refund that way).
Awesome thanks, I was able to snag LA-Cancun for 5k miles
There are no change fees but fare credit on the usual Wanna Get Away fares can only be used on the person for whom the reservation was booked for.
