UPS has secondary sorts at Ontario, CA, Rockford, IL, Philly, PA, Dallas, TX, and Columbia, SC. A typical trip domestic is a Sunday commercial out of Louisville to position for a Monday night flight and get done on Saturday night...then off the next week. You go on duty around 9pm, fly to the sort, sit around for 3 or 4 hours, and fly out of the sort. International keeps you away from home 12 to 14 days, usually long duty days with 24 hour layovers, all over the world. I'm senior in my seat, so I usually get some of the best trips and get pretty much my choice. Currently, I'm away from home about 10 days out of 28 and fly between Seattle and Vancouver, BC.
