- If the connection is missed

- First and last departure
- The first service of the day leaves Chicago at 06:12 and the last at 17:26, across 12 departures. The return direction keeps its own timetable, so the times back are not these times reversed.

Where these numbers come from
Observed service A carrier record shows this named operator serving this named pair, and we carry that through unchanged.
Schedules, seat counts and fares are generated by our own model until the supplier contracts are signed. Places, coordinates, operators, which operator serves which pair, and every distance are real. We would rather say that on every page than let a modeled number pass for a filed one.
