It's actually 10 off and 2 commuting days, so in all technicality, it's 12 off in a row. Plus a 24 vacation bank that you can tap into at anytime and take as many days as you want up to 24 per annum. So many guys (if not the majority) convert their days off to 14 by pulling 2 every month from the vacation days. So it more like 16 on 14 off.
To take a vacation many bid a back-to-back, like 33 on followed by 28 off. Some guys actually only do back-to-backs a whole year long.
Additionally, when you are on your days on in NRT, you still get a few days off (blank days or more like "legality" days off, like 1 in 7 or during pairing conflicts etc.). I've noticed in a stretch of 17, on average you'll get additionally 2-3 off in NRT between your duties.
BTW, all of the above assumes you are a standard N. American, Australian or European commuter. We have many guys that live locally in the Asian region and bid like a week on week off. (more like 9 on / 7 off )
