Flight system

[USA]

I'd say a time limit so it can be somewhat comparable between short and long haul flights. My question is how this will work with in terms of scheduling the next flights up. Meaning after the JFK-CLT leg are you going to be able to set a departure time for the CLT-ATL leg and will there be some sort of turnaround expectation? So is it just going to be automatic (no ground time), a set time per aircraft type (no customization), or are people going to be able to set a ground time in which case what will that number be compared to do determine likelihood that the next flight leaves on-time, etc.?
