Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with American Airlines.
American on DFW to DTW draws a C. About one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 1,621 flights, with a median arrival 1 minute late.
The national on-time rate over the same period is 77.6%, so American on DFW to DTW runs 10 points behind the country as a whole. Across a thousand flights that is about 101 extra late arrivals.

These figures cover 1,621 flights between July 2025 and June 2026. Beyond the headline rate, 13.0% 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 DFW to DTW
American flew 1,621 of the 3,506 flights on DFW to DTW, about 46% of it. Its 67.5% on time is 8 points worse than the route as a whole, which runs 75.6%. Ranked by on-time rate it is last of five carriers on the route, where the range runs from Envoy at 94.7% to American at 67.5%. Three of those carriers flew fewer than 365 flights here, so treat their positions as rough.
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.

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 30 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am318 flights84.3%
- 8am–11am151 flights83.8%
- 11am–2pm307 flights63.5%
- 2pm–5pm280 flights60.0%
- 5pm–8pm435 flights60.5%
- 8pm–5am130 flights54.8%
Scale runs 45% to 90%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 54.8% on time, against 84.3% 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 5pm–8pm window is the busiest, with 435 flights scheduled in it.
Across the year
American on DFW to DTW through the year
June is the worst month at 58.6% on time, 20 points below September, the best at 78.2%. 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. May was the busiest month here, with 151 flights.
Across the week, Friday is the strongest day at 71.2% on time and Sunday the weakest at 59.4%. 12 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 50% of the 36,000 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.
- 50%Late-arriving aircraft
- 32%Carrier
- 9%National Airspace System
- 9%Extreme weather
- 0%Security
50% 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 36,000 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 35,883 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 84.3% on time here.
Cancellations run at 2.53%, against 1.81% 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 costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 13.0% 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 986 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 75.9% on time across 1,621 flights, 8 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 8 points of difference.
The sample behind these figures is 1,621 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 American on DFW to DTW
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 78.2% on time and June 58.6%, a swing of 20 points. If the dates move at all, move them out of June before you think about anything else. 1,577 completed flights over 12 months sit behind that.
