American Airlines at Jacksonville lands a B, 3 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 6,909 flights, of which Delta Air Lines flew 5,257 at 84.2% on time.
Measured against the airport rather than the country, American Airlines runs half a point ahead of the 79.6% weighted average across all carriers at JAX. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

Against the competition
Every carrier at JAX, ranked
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 84.2% of the time; Frontier Airlines manages 63.8%. Sample sizes sit next to every figure, because a two-point gap across 694 flights means less than a ten-point one.

Route by route
Where American Airlines flies from JAX
American Airlines operates 7 routes out of JAX with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window
Best time of day for this operation
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 26 points, against 20 points between the best and worst carrier.
- 5am–8am2,230 flights90.4%
- 8am–11am1,058 flights87.4%
- 11am–2pm1,051 flights85.3%
- 2pm–5pm817 flights70.2%
- 5pm–8pm1,448 flights64.4%
- 8pm–5am305 flights64.9%
Scale runs 55% to 95%.
The 5pm–8pm window is where this operation falls apart: 64.4% on time, against 90.4% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5am–8am window is the busiest, with 2,230 flights scheduled in it.
Across the year
Seasonal pattern
June is the worst month at 73.8% on time, 10 points below April, the best at 84.0%. 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. October was the busiest month here, with 701 flights.

45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 121,000 reported delay minutes here, that single category outweighs weather by 9 to one. The split is drawn from 120,514 reported delay minutes.
Cancellations sit at 1.78% against a national 1.89%, which is ordinary. Diversions add another 0.26%.
8.2% 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 sample behind these figures is 6,909 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.
Put together: avoid the 5pm–8pm departure. It runs 64.4% on time against 90.4% for the 5am–8am slot, and that 26 points is the largest single thing you control here. Delta Air Lines is the strongest operator if the fares are close. 6,768 completed flights over 12 months sit behind that.
Common questions
American Airlines at JAX
How often is American Airlines at JAX delayed?
About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 19.8% of the 6,909 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
Which airline is most reliable on American Airlines at JAX?
Delta Air Lines leads at 84.2% on time across 5,257 flights. Frontier Airlines is at the other end on 63.8%, a gap of 20 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on American Airlines at JAX?
The 5am–8am departure window is the strongest at 90.4% on time. The 5pm–8pm window is the weakest at 64.4%, 26 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 American Airlines at JAX?
June is the weakest month at 73.8% on time, compared with 84.0% in April. Across the year that is 10 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
