These figures cover 369 flights between September 2025 and August 2026. The median arrival is 9 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Departure window
When Delta runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 369 flights.
There are not enough flights in each departure window to split Delta's TVC to DTW record by time of day without the percentages moving on noise. The headline rate of 83.4% is the reliable figure here.
Across the year
Delta on TVC to DTW through the year
December is the weak month at 48.4% on time, against 100.0% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. September was the busiest month here, with 34 flights.
Across the week, Saturday is the strongest day at 87.5% on time and Friday the weakest at 76.9%, a spread of 11 points.

Delay causes
Why Delta runs late on this route
Carrier accounts for 53% of the 4,583 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Carrier
- 35%National Airspace System
- 10%Extreme weather
- 2%Late-arriving aircraft
The largest share of delay minutes, 53%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,440 of the 4,583 delay minutes reported here. The split is drawn from 4,583 reported delay minutes.
35% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,600 minutes out of 4,583, against a national NAS share of 21%.
Cancellations sit at 2.17% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
5.8% 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 a little over an hour, which a normal layover absorbs.
At 207 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 77.3% on time across 369 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. 369 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 Delta on TVC to DTW
Put together: treat all of this as provisional. 369 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 83.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 361 completed flights over 12 months sit behind that.
