It's not just a question of whether they generate more GHG per mile, it's a question of whether they generate more GHG per hour. You wouldn't make a thousand mile trip over the weekend by car, but people don't bat an eye doing it by plane.

You wouldn't take that by car? I would and I'm not an outlier in the midwest - many of us do it all the time. There just isn't a better option for a family. Flying would cost thousands of dollars more and you risk missing a connection and the trip taking even longer. The train doesn't really go many places in the US and isn't cheap. Just get in the car and travel on your own time - it is relaxing after a while. If you get bored stop to see some small town attraction for an hour and continue on.
