Redeeming Points For Travel On Free Spirit Account

It could be that the availability for the reedeming points club has been sold out for direct flights, so the next available flight for those in the reedeming points club is one with a layover on the way to your final destination. Also, It could be that people reedeming with points only get the option of making a layover, versus paying with money for direct flights or one with a layover. It's a silly concept, but unfortunately that's  how this airline may work. Always try again later as well. Their schedules constantly change.
