What is the gouge on the back end deviation? I have had guys tell me not to deviate until I am at the city where the DH starts. The idea, I am told, is that if they re-route or you arrive late, they have to rebuild the DH part of the trip for legal rest and if you are already deviating, they don't and you could lose out on money. Is there any other reason to do this? This doesn't seem right to me because one time we landed late at an airport with very limited airline service, and as we were leaving the plane, a ramp agent told us to call crew scheduling. We were thinking they were going to add another leg, but he called to tell us we were too late to make the scheduled DH and he rebuilt the trip. He said he saw that I was originally deviating and asked if I would still like to deviate. I deviated again and still got the extra pay for the new DH time. Was this scheduler the exception rather than the norm? Am I missing something else?
