Answer these questions for yourself..

What is your strategy with this commute when your report time is 7am?
When you are finished after 9-10pm, or later?
When you have back to back trips (1 night off in between), or 1 day off between trips?

I drive 1:10 now, and have to leave 2 hours prior to account for traffic and airport overhead, and that's long enough to where I don't care to make the commute any more than 1.5-2x a week.
