CLT connection times, Charlotte
 

My connection time is 50 minutes from Concourse E to Concourse C. Will I need to run, ask for a courtesy shuttle, or just move along at a nice clip?

Based on my experience, if you land on time, you'll be fine if you just move along at a nice clip.

A courtesy shuttle for what? Are you physically disabled? 50 minutes is PLENTY of time in my own experience especially if flights are on time.

I'd be more concerned about how far BACK in the aircraft I was seated than anything else.

If you are at the very end of Concourse E and the very end of C, walking at a good clip using the numerous moving walkways should take no more than 10-12 minutes.
