Depends on the week/month I build for myself. Sometimes I have 7-8 days off in a row, go work for 4 or 5 days, then off again for a week. Then work another 4 day and a 3 day at the end of the month. During those days off, sometimes my wife and I travel and other times we just take it easy around the house and go to the beach.
Other months, where I decide to work more (like this month), it's your typical 4 days on, 2-4 days off routine. All of my trips are commutable on both ends and usually credit pretty decent (18-22 hours).
The answer to your question will vary greatly depending on who you ask and what airline they work for.
