JetSmarter has been mentioned recently throughout Flyertalk. I have been a subscriber for about four months, about to take my sixth flight with them.

What is the current feeling about the service up until now? Overall, I have been quite pleased, but there has been some discussion as to whether or not the JetShuttle flights are a good business model.

Thoughts?
