In 1982 (or so), CO had startup service to JAX from IAH. Did a 24 hour turn for $38 RT total (no PFC's, etc then )& they were giving triple miles. It was hard to get availablity as this was long before the internet. Was in grad school & called many times until I got through. Was willing to do a quick turn to get the miles. A few people called me crazy at the time but the triple miles helped me to get an award to Australia two years ago. I wasn't so crazy!
