The Airways folks have been using their system for years too. It actually started at Piedmont if I am not mistaken and was incorporated during that merger many years ago. This is not new. It should also be noted that the West pilots and the East pilots both like the system. It takes an act of God for them to agree except in this case. That says a lot about how well the system works. Also, West was very much against the idea when it was put in place for them during the so called merger of US Airways and AWA.
