In the AM you usually just do early AM delveries and that's it. After you are done with EAM deliveries, extra work like shuttling packages or delivering airs goes by senority. There's more pressure, and it's probably gonna be different stops/areas everyday...PM air is going to be the same pickup stops everyday. With the occasional delivery, shutting package(s) or on demand air pickup. It's less stressful, but you do need to be back on time, so your airs can get on the plane. In my building, you can get more hours on PM than AM. Though it is harder to get a PM spot, as it is typically a 22.3 FT job. Plus not as many drivers. AM there always seems to be a need for drivers.
