Things got a little squirley with my scheduled late departure from TYS Monday afternoon, so I decided to SDC to an earlier flight. I tried on-line and got the changes had to be done over the phone screen, so I called the Diamond Line and was quoted a 2 hour wait, which would have put me past the departure time for the earlier flight.

Fortunately, my office is 5 minutes from the airport, so I just ran down there and had the agents at the check-in counter take care of it...easy peasy- it took about 20 minutes of my time!
