<p>Colorado Springs Shuttle LLC is an option. However, we have always been able to find a flight that transfers to CS at about the same cost. I do always look for a transfer from Denver if son has to get back for class since I don’t want him marooned in Dallas or Cincinnatti if there is a problem and this way the shuttle is an option. With the block plan, it can be a problem to miss one day of class. Coming home, I am not as particular unless it is a tight schedule. We have not had any problems yet.</p>
