Probably not. I don't remember (and correct me LB) but I think she was in CA. A train trip from CA to where she is is something like 2 or 3 days long, so flight is better so she has time to rest before going back to work on Monday.
Why are you surprised she utilizes other transportation means? She does enjoy train travel but when there are time constraints then the best means possible for getting from Point A to Point B is a better path.
