Departure window
When American runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 12 points, against half a point between the best and worst carrier.

- 8am–11am—
- 11am–2pm263 flights67.5%
- 2pm–5pm138 flights56.0%
- 5pm–8pm—
- 8pm–5am—
Scale runs 50% to 75%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 67.5% on time, ahead of 2pm–5pm at 56.0%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 11am–2pm window is the busiest, with 263 flights scheduled in it.

Share of 389 completed flights by arrival against schedule.
34 of 156 late departures made up the time and arrived on time, 22% of them. In the other direction, 20 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ORD.

Worst days for American on JAC to ORD
The latest arrival of the period was on 6 August 2026, 23 hours 32 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 August 2026 | 23 hours 32 minutes | Carrier |

Delay causes
Why American runs late on this route
Late-arriving aircraft accounts for 57% of the 17,000 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Late-arriving aircraft
- 25%Carrier
- 10%Extreme weather
- 9%National Airspace System
- 0%Security
57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 17,000 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 17,411 reported delay minutes.
Cancellations sit at 1.50% against a national 1.89%, which is ordinary. Diversions add another 1.50%.
Connections and stage length
What a delay here costs
19.8% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 1,162 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg is a different operation and performs like one: it runs 68.3% on time across 401 flights, 5 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 5 points of difference.
One caution: this is a thin sample. 401 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking American on JAC to ORD
Put together: treat all of this as provisional. 401 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 63.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 389 completed flights over 12 months sit behind that.
