Delta on DTW to TVC lands a B, level with the national rate of 77.3%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 369 flights, with a median arrival 7 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Delta on DTW to TVC from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

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.
The overnight block holds up unusually well at 76.9% on time across 362 flights. Red-eyes fly into empty airspace and empty gates, and they are the first rotation of the aircraft's day rather than the last. The 8pm–5am window is the busiest, with 362 flights scheduled in it.
Across the year
Delta on DTW to TVC through the year
July is the worst month at 61.3% on time, 36 points below October, the best at 96.9%. 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. September was the busiest month here, with 34 flights.
Across the week, Friday is the strongest day at 88.5% on time and Thursday the weakest at 69.2%, a spread of 19 points.

Delay causes
Why Delta runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 5,008 reported delay minutes.
- 35%Late-arriving aircraft
- 33%Carrier
- 23%National Airspace System
- 9%Extreme weather
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,008 reported delay minutes here, that single category outweighs weather by 4 to one. The split is drawn from 5,008 reported delay minutes.
Cancellations sit at 1.90% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
9.1% 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.
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 8pm–5am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 83.4% on time across 369 flights, 6 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 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 DTW to TVC
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 77.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 362 completed flights over 12 months sit behind that.
