Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2091, check with Delta Air Lines.

DL 2091 earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 50 minutes. That rests on 349 flights, with a median arrival 11 minutes early.

Set against the rest of the country, DL 2091's record is 9 points better than the US average of 77.6%. That gap is worth roughly 87 fewer late arrivals for every thousand flights.

These figures cover 349 flights between July 2025 and June 2026. The median arrival is 11 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 2091 flies

DL 2091 flies SYR to DTW without a single fixed slot. Its most common scheduled departure was 05:50, used on 122 of 349 flights, with 06:00 (106 flights) and 06:10 (66 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 05:50 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2091 runs 3 points worse at 86.3%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 2091 next to SYR to DTW

Across the year

DL 2091 quarter by quarter

DL 2091 did not run the same all year. Its best quarter was Jul–Sep 2025 at 97.8% on time and its weakest Oct–Dec 2025 at 75.9%, a swing of 22 points on roughly 87 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 2091 did best on Thursday at 90.0% on time and worst on Wednesday at 78.0%. Each day rests on about 50 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2091 runs late

One category carries most of the weight here. National Airspace System accounts for 43% of the 2,349 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.

Extreme weather

The largest share of delay minutes, 42%, 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 989 of the 2,349 delay minutes reported here. The split is drawn from 2,349 delay minutes reported on DL 2091.

Cancellations sit at 1.72% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.8% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

The same number turns up on one other city pair in the data, including ATL to VPS (1), but none flew often enough under DL 2091 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SYR to DTW only.

One caution: this is a thin sample. 349 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 2091

For a booking, read DL 2091 as 86.3% on time with 1.72% cancelled over 349 flights. Those are rates from the past twelve months, not a forecast for any particular day.
