I have some questions about this.. My sister is going to be renting a place north of Orlando (every year) from mid-October until mid-April.. In Oct., she and her son will drive down together (so she can have her car there) and then she will purchase a ticket for her son on SW for him to fly back.. In April they will do it again in reverse.. She also plan on flying up here around Christmas for a few days and then flying back to Orlando.. All flights will be on SW, so how can she best benefit from the RR program? And do the rewards accumualte - or does she have to use them within a year? Thanks!
