I have been accumulating SWAir rapid rewards points on my Hampton Inn business stays because of their fast accumulation to a free voucher. I now have 5 round trip vouchers, soon to be 6 and would prefer to trade them for another airlines round trip vouchers. The closest SWA is 4 1/2 hours away and it has become a pain to drive there to fly. Does anyone know of a site that I could exchange my vouchers for another airlines, say Airtran or Delta? Any suggestions? Thank you
