the sub not making it back in time will be more of a problem for the sub than it will be for either you or the size of your route. i have never heard of this being any kind of concern. years ago we had a sub in a similar situation, another route opened up, and he was allowed to switch routes. i have heard the supervisors talking that it was one of the biggest mistakes they ever made allowing him to stay. over 15 years later, now as a regular for the past 4 years, he still has problems making dispatch on occasion, always has 2080 issues, and now in the first week of the new guarantee year, has asked to take lwop looking ahead to avoid problems for next year.
