You post that over and over again. Can you site a single source. The only source I have ever seen was the company requested it for trip coverage on 4 day and longer trips both domestic and international. We asked for and received two offsets for ALV 15 to prevent job loss which were including known absences in determining when a reserve is full and reducing when a reserve is full to the reserve guarantee from the ALV. So far it looks like we got the better deal!
