A lot of stuff depends on the contract. 6 on 1 off is pretty common and can be expected at least once a month where I'm at. Some CBA's prohibit less than 2 days off at a time. So it depends.

From talking to people it seem like 1:30 is a pretty common call out. One place I worked at 1:00 my current place is 1:30 and I've heard of 2:00. If you have a 2:00 call out you need to live closer than 2:00 from the airport. You have to remember that you have to get dressed, drive to the airport and be at certain point (plane, crew room, gate, terminal) whichever is stated in the CBA by that call out time. Its usually a good idea to stay packed all the time so you only have to worry about throwing on the uniform. Also if you decide to leave your house then take your bags and uniform in the car with you just in case you get called so you can save time. I had a great time my first year on reserve. We were pretty well staffed. Reserve guys didn't fly much and there was a good amusement park 30 mins from my airport. A couple of guys from the crashpad all got season passes. We got way more than our moneys worth outta the passes until school got out and the lines got long...So reserve is what you make out of it.

Once again min call out time is rarely used, but it does happen. Most times I get called at least 24 hours out. I do get the "how fast can you get there" calls on home reserve a few times a year though.

Another thing that limits how far away you can sneak away from the airport is the size of the airport. If based at an outstation you can live farther away because time from parking the car to inside the terminal is usually pretty short. If based at a hub it can take quite a while to get from the employee lot to the terminal (30-45 mins at some airports) so that drastically cuts into the distance you can live from the airport.

Anyways good luck. Hope this helps shed some light on what you're getting yourself into. If you have any more questions go ahead and ask.
