When I was there a few years ago the typical schedule was basically no schedule. You flew out and backs, mostly to South America. I did spend 5 whole days once in Luxembourg, but that was about it. (There was an overnight in Santiago, and once the airplane broke in Bogota, so I guess that counted as an overnight)
The South America trips, mostly to Bogota, were out and back within 8 hours or so. So no "2 week on, 2 week off" type schedule. Hence, not commutable.
It's possible things have changed somewhat over the past 4 years, but my friends still in the company say that things pretty much stayed the same.
If you happen to live in Cuba, er Miami, and English is your second language, it's not a bad place to be.
For what its worth.
