Book the early departure. Flights leaving between 5am–8am arrive on time 77.1% of the time, against 66.9% for the afternoon window. That is 10 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 428 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 23 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
August is the worst month at 59.2% on time, 23 points below May, the best at 82.4%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. July was the busiest month here, with 100 flights.
Across the week, Thursday is the strongest day at 76.0% on time and Sunday the weakest at 60.7%, a spread of 15 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 56% of the 37,000 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Late-arriving aircraft
- 35%Carrier
- 5%National Airspace System
- 4%Extreme weather
- 0%Security
56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 37,000 reported delay minutes here, that single category outweighs weather by 15 to one. The split is drawn from 37,210 reported delay minutes.
The largest share of delay minutes, 35%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 13,000 of the 37,000 delay minutes reported here.
Cancellations sit at 2.27% against a national 1.89%, which is ordinary. Diversions add another 1.20%.
Connections and stage length
What a delay here actually costs
15.1% 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 1,047 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 62.6% on time across 749 flights, 6 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 6 points of difference.
One caution: this is a thin sample. 749 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 this route
Put together: treat all of this as provisional. 749 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 68.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 723 completed flights over 12 months sit behind that.
Common questions
JAC to DFW questions
How often is JAC to DFW delayed?
About one flight in three arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 31.4% of the 749 flights in this analysis, against 22.7% nationally. Delayed flights are late by about 2.7 hours on average.
How reliable is JAC to DFW compared with the rest of the country?
68.6% of flights arrive on time here against a national 77.3%, a difference of 9 points against it. That is worth a C on this site's grading scale.
What time of day has the fewest delays on JAC to DFW?
The 5am–8am departure window is the strongest at 77.1% on time. The 2pm–5pm window is the weakest at 66.9%, 10 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are August delays on JAC to DFW?
August is the weakest month at 59.2% on time, compared with 82.4% in May. Across the year that is 23 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
