Hey mike,
As an SO, your rosters are usually pretty good that they do allow you to commute, especially if your hired onto the 744 fleet. Using the system as well, can also help you get a good block of days off, to the point that you could probably commute bak home nearly every month.
Having said that, our flights to the west coast are usually always full so you have to also be aware that even though you may have the days off, you may not be able to get on the flight due to there being no seats available or due to there being a weight restriction.
Trying to commute as an FO is another story, it will be almost impossible to commute on a regular basis as the rosters are very tight. Again, you would need to look at upgrading onto the 777 fleet as it would allow you to later on request a change of fleet back to the jumbo to make commuting easier. Stay away from the airbus if you plan on commuting to the states!!
Hope this helps,
cheers
