I have received a lot more pms than i expected, i promise to reply to everyone. please bear with me as i only have access to mfk through my phone during the day.
there are not many blackout dates for these tickets, the list of dates is on the SWA website. however SWA only allots so many seats for rapid rewards tickets and once the quota is filled for each flight they become unavailable. from the website;
Rapid Rewards Awards will be subject to seat restrictions, and seats will not be available for Award travel on all flights on all days. It may be particularly difficult to secure a seat when trying to make reservations around holiday periods such as Thanksgiving, Christmas, New Years, Presidents Day, some weekends during Spring Break, Memorial Day, July 4th, and Labor Day to popular destinations.
thank you for understanding.
