Our company lists time-away-from-base with each available monthly schedule. For June, the highest are around 350-370 hours, and the lowest are in the 290s. Think about 24 hours per day times 30 days to see that there are around 720 hours in a bid period. If you are on the company's clock for half of that time, you can imagine what's left. Keep in mind that of the other half of the month left over, you will spend at least a third sleeping.

Work rules determine time away from home in a big way; for instance, is the company allowed to give you 10 days off with one day at a time spread over 10 instances? That stinks. Hopefully they require that days off be at least paired. On reserve, is the call-out time (how long you have to get to the airport after a phone call) one hour, or 24? As you can see, there are lots of factors that are really going to impact quality of home life, and perhaps the largest is where home is with regard to where your domicile is. If you are home at the end of each trip, you will have more time there than if you have to try to catch a flight to some other place. Being on reserve at your house isn't so bad either, as long as you are good at entertaining yourself with hobbies and other interests.
