These figures cover 365 flights between September 2025 and August 2026. The median arrival is 6 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.

A 08:30 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 1113 runs level with that at 85.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

DL 1113 quarter by quarter

DL 1113 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.7% on time and its weakest Jan–Mar 2026 at 80.0%, a swing of 17 points on roughly 73 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 1113 did best on Monday at 92.5% on time and worst on Thursday at 78.8%. Each day rests on about 52 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Arrival by arrival

How late DL 1113 runs when it is late

DL 1113 often beats the schedule: 92 of 364 completed flights, 25%, arrived 15 minutes or more early. The 52 late arrivals split 22 under half an hour, 18 between 30 and 60 minutes, and 12 an hour or more.

Share of 364 completed flights by arrival against schedule.

4 of 25 late departures made up the time and arrived on time, 16% of them. In the other direction, 31 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at DEN.

The worst days

Worst days for DL 1113

The latest arrival of the period was on 29 January 2026, 4 hours 52 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.

Delay causes

Why DL 1113 runs late

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 2,662 reported delay minutes.

National Airspace System
41%
Carrier
40%
Extreme weather
15%
Late-arriving aircraft
4%

Extreme weather accounts for 15% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.5 times the usual weather exposure. The split is drawn from 2,662 delay minutes reported on DL 1113.

Cancellations are rare at 0.27%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.3% land an hour or more behind schedule, against 8.3% 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 1,123 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.

Every one of the 365 flights under DL 1113 in the data flew DTW to DEN. 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. 365 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 1113

For a booking, DL 1113 has one of the better records a US domestic flight can show: 85.7% on time and 0.27% cancelled. That is a base rate, not a promise about any single day.
