Living at home watching my father commute when I was younger, and now being a commuter myself, I don't believe it's worth it. Especially if your junior. (see earlier posts)

Living in base consider:

-an extra day per week at home.
-option to fly locals and be home EVERY night.
-no stress about overbooked flights when your trying to get to work (or home)-this applies to "no-policy" airlines.
-You can pick up Standups and be home durring the day.
-much less to pack for a trip.

Im sure there is more....but I cant think of them right now. But to me it's just not worth it. As stated earlier, with airlines overbooking, canceling, and having to fight for a seat with other commuters, it's a pain. I cant wait till I'm done with it.
