Jeb summed up my position really well. I use whichever mode of transportation works best with my schedule and finances. I usually only take a train long distances when it's part of my vacation and I'm doing it for the scenery. It's much more convenient to fly.I fly quite a bit more than I take the train. There are far too many markets where a two-hour flight is multiple days by train due to low speed, low frequency, and out-of-the-way routes. Since I do enjoy flying as well as taking the train, there isn't a strong hesitation against flying, and I simply don't have the time far too often to take the train.
If I had the time and the money, I'd probably take the train [...]
But given the time constraints and the frustrating intercity rail network, I've found ways to work around the issues with flying and will typically do that on longer trips unless I have extra time and want to make the train trip part of the vacation.
As far as regional trips, I have a lot of frustration with the current Michigan Services schedule. I find myself driving to/from Chicago and Detroit more often than not. I would prefer to take the train, but the schedule simply does not work for me.
I feel the same way about traveling to the east coast. As much as I'd love to take the train, the schedule is terrible. If I could board at 9 a.m. and be there around 9 p.m, I'd be all for it.
