Pacer to Sabre problems were minimal. The first day was a little dicey but that had more to do with res-decs issues and takeoff numbers. Most issues were pretty well taken care of in less than week , can't say that for shares after a YEAR. IT SUCKED THEN IT SUCKS NOW. I would much rather have a system where I tell it what I want rather than it deciding if ,when and how I might obtain it.
