These figures cover 364 flights between July 2025 and June 2026. Beyond the headline rate, 8.5% 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.
Schedule
When DL 2602 flies
DL 2602 flies DTW to LGA without a single fixed slot. Its most common scheduled departure was 14:03, used on 49 of 364 flights, with 14:05 (42 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 14:03 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 2602 runs 3 points better at 75.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 2602 quarter by quarter
DL 2602 did not run the same all year. Its best quarter was Jan–Mar 2026 at 80.2% on time and its weakest Apr–Jun 2026 at 70.0%, a swing of 10 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, DL 2602 did best on Wednesday at 84.3% on time and worst on Friday at 67.3%. Each day rests on about 52 flights, so a gap of 17 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 2602 runs late
One category carries most of the weight here. National Airspace System accounts for 66% of the 6,546 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.
- 66%National Airspace System
- 25%Carrier
- 8%Late-arriving aircraft
- 1%Extreme weather
66% 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 4,333 minutes out of 6,546, against a national NAS share of 21%. The split is drawn from 6,546 delay minutes reported on DL 2602.
Cancellations sit at 2.47% against a national 1.81%, which is ordinary. Diversions add another 0.55%.
Connections and routes
What a delay on this flight costs
8.5% of arrivals land an hour or more late, close to the national 8.1%. 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.
The 502 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.
Every one of the 364 flights under DL 2602 in the data flew DTW to LGA. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 364 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.
