This route lands a B, 2 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 1,840 JAX to DFW flights, with a median arrival 9 minutes early.
Best time to fly JAX to DFW: a 5am–8am departure, ideally on a Tuesday. Flights in that window arrived on time 90.4% of the time and Tuesday flights 84.3%, against 79.3% for the route overall.
The US average over the same twelve months is 77.3%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Across the year
When delays peak on this route
This route's year swings by 12 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.
June is the worst month at 73.2% on time, 12 points below September, the best at 85.4%. 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 183 flights.
Across the week, Tuesday is the strongest day at 84.3% on time and Sunday the weakest at 72.8%, a spread of 12 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 43% of the 36,000 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Late-arriving aircraft
- 42%Carrier
- 10%National Airspace System
- 5%Extreme weather
- 0%Security
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 36,000 reported delay minutes here, that single category outweighs weather by 9 to one. The split is drawn from 35,713 reported delay minutes.
The largest share of delay minutes, 42%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 15,000 of the 36,000 delay minutes reported here.
Cancellations run at 2.61%, against 1.89% nationally. That is about one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and stage length
What a delay here actually costs
8.9% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
The 917 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 64.8% on time across 1,840 flights, 15 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 15 points of difference.
The sample behind these figures is 1,840 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 85.4% on time and June 73.2%, a swing of 12 points. If the dates move at all, move them out of June before you think about anything else. 1,784 completed flights over 12 months sit behind that.

How reliable is JAX to DFW compared with the rest of the country?
79.3% of flights arrive on time here against a national 77.3%, a difference of 2 points in its favour. That is worth a B on this site's grading scale.

The 5am–8am departure window is the strongest at 90.4% on time. The 5pm–8pm window is the weakest at 57.7%, 33 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 June delays on JAX to DFW?
