Departure window
The best time of day to leave DTW in June
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 20 points, against 25 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,197 flights89.6%
- 8am–11am2,465 flights86.4%
- 11am–2pm1,231 flights78.8%
- 2pm–5pm2,021 flights75.9%
- 5pm–8pm1,187 flights69.6%
- 8pm–5am1,768 flights71.8%
Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 89.6% of the time, against 69.6% for the evening window. That is 20 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 2,465 flights scheduled in it.
Across the week, Wednesday is the strongest day at 82.5% on time and Sunday the weakest at 72.1%. 10 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at DTW in June
The choice of carrier is not cosmetic here. Republic Airways arrives on time 86.0% of the time; Southwest Airlines manages 61.2%. Sample sizes sit next to every figure, because a two-point gap across 382 flights means less than a ten-point one.

| Delta Air Lines | 5,200 | 78.0% | 69 min | 1.40% | B |

Delay causes
What held DTW up in June
One category carries most of the weight here. Carrier accounts for 50% of the 147,000 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%Carrier
- 22%Late-arriving aircraft
- 20%National Airspace System
- 7%Extreme weather
- 0%Security
The largest share of delay minutes, 50%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 74,000 of the 147,000 delay minutes reported here. The split is drawn from 147,398 reported delay minutes.
Cancellations sit at 1.43% against a national 1.65%, which is ordinary. Diversions add another 0.39%.
7.7% of arrivals land an hour or more late, close to the national 9.7%. That is the figure that decides a connection, and it says 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.
