Don't expect to "talk" to Capt Rush.. You wont have a chance. His mouth never stops flapping. Also I wouldn't ask him anything about commuting as he always shows up at the gate 5 mins prior to departure. Also I wouldn't buy to many drinks as he will come to expect it all the time. I have to say though he is a "nice enough" guy.
In the 4 years I was based in DTW I only saw him on the TYS commute a half dozen times.

I've been a PCL/TYS commuter for 10 years.
