Share of 394 completed flights by arrival against schedule.
22 of 103 late departures made up the time and arrived on time, 21% of them. In the other direction, 44 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 JAC.
The worst days
Worst days for American on ORD to JAC
The latest arrival of the period was on 17 March 2026, 20 hours 20 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 |
|---|---|---|
| 17 March 2026 | 20 hours 20 minutes | Carrier |
| 14 July 2026 | 20 hours 5 minutes | Carrier |
| 3 September 2025 | 17 hours 54 minutes | Carrier |
| 29 July 2026 | 10 hours 3 minutes | Late-arriving aircraft |
| 24 February 2026 | 6 hours 44 minutes | Late-arriving aircraft |
Delay causes
Why American runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 14,000 reported delay minutes.
- 41%Carrier
- 36%Late-arriving aircraft
- 18%National Airspace System
- 5%Extreme weather
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 14,000 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 13,871 reported delay minutes.
The largest share of delay minutes, 41%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,687 of the 14,000 delay minutes reported here.
Cancellations sit at 1.00% against a national 1.89%, which is ordinary. Diversions add another 0.75%.
Connections and stage length
What a delay here costs
13.7% 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 63.5% on time across 401 flights, 5 points below 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 ORD to JAC
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 68.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 394 completed flights over 12 months sit behind that.
