On the road

So this is my last week at my current job. I didn't manage to finagle much time off between jobs, but I did get Friday off, so I'll do my 17 miler then so I'm fresh for my 6 am flight on Monday. The question will be the on-going training once I'm traveling. I know I won't get up at 2 am in order to get in a long run before a 6 am flight. I know I'll be fried after taking a red eye home and not want to run then either. Any road warriors out there? Any advice?
