DL 2822 lands a B, level with the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 326 flights, with a median arrival 10 minutes early.

These figures cover 326 flights between July 2025 and June 2026. The median arrival is 10 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.
Schedule
When DL 2822 flies
DL 2822 flies DTW to STL without a single fixed slot. Its most common scheduled departure was 15:50, used on 65 of 326 flights, with 16:00 (59 flights) and 16:25 (34 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 15:50 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 2822 runs 5 points better at 77.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 2822 quarter by quarter
Quarter by quarter DL 2822 held fairly steady: 75.6% in Jul–Sep 2025, 76.3% in Oct–Dec 2025, 79.2% in Jan–Mar 2026 and 80.0% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202582 flights75.6%
- Oct–Dec 202578 flights76.3%
- Jan–Mar 202677 flights79.2%
- Apr–Jun 202689 flights80.0%
Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2822 did best on Tuesday at 86.0% on time and worst on Friday at 70.5%. Each day rests on about 47 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 2822 runs late
One category carries most of the weight here. Carrier accounts for 58% of the 4,169 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.
- 58%Carrier
- 22%Late-arriving aircraft
- 13%National Airspace System
- 7%Extreme weather
The largest share of delay minutes, 58%, 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 2,408 of the 4,169 delay minutes reported here. The split is drawn from 4,169 delay minutes reported on DL 2822.
Cancellations sit at 1.84% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
6.9% 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 about an hour, which a normal layover absorbs.
The same number turns up on two other city pairs in the data, including STL to DTW (90) and LGA to BOS (16), but none flew often enough under DL 2822 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DTW to STL only.
One caution: this is a thin sample. 326 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 DL 2822
