Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with American Airlines.
American on JAC to ORD draws a D. Roughly one flight in three arrives at least 15 minutes late, and the typical late arrival is close to two hours behind schedule. Build slack into anything you connect to. That rests on 397 flights, with a median arrival 2 minutes late.
The national on-time rate over the same period is 77.6%, so American on JAC to ORD runs 14 points behind the country as a whole. Across a thousand flights that is about 145 extra late arrivals.

These figures cover 397 flights between July 2025 and June 2026. Beyond the headline rate, 18.2% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
American against every carrier on JAC to ORD
American flew 397 of the 818 flights on JAC to ORD, about 49% of it. Its 63.1% on time is 7 points worse than the route as a whole, which runs 69.8%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from United at 76.2% to American at 63.1%.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

| United Airlines | 421 | 76.2% | 117 min | 2.14% | B |

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 11 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

- 8am–11am—
- 11am–2pm263 flights66.9%
- 2pm–5pm134 flights55.7%
- 5pm–8pm—
- 8pm–5am—
Scale runs 45% to 70%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 66.9% on time, ahead of 2pm–5pm at 55.7%. 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.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 63.1% on time across 397 flights.
American on JAC to ORD did not run the same all year. Its best quarter was Oct–Dec 2025 at 80.0% on time and its weakest Jul–Sep 2025 at 55.4%, a swing of 25 points on roughly 99 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
Across the week, Tuesday is the strongest day at 74.5% on time and Monday the weakest at 56.4%. 18 points is a smaller lever than departure hour, but it is free.
Delay causes
Why American runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 57% of the 15,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 57%Late-arriving aircraft
- 19%Carrier
- 15%National Airspace System
- 9%Extreme weather
- 0%Security
57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 15,000 reported delay minutes here, that single category outweighs weather by 6 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 15,186 reported delay minutes.
Cancellations sit at 1.01% against a national 1.81%, which is ordinary. Diversions add another 2.02%.
Connections and stage length
What a delay here costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 18.2% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg is a different operation and performs like one: it runs 69.1% on time across 397 flights, 6 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 6 points of difference.
One caution: this is a thin sample. 397 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. 397 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 63.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 385 completed flights over 12 months sit behind that.
