Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2163, check with Delta Air Lines.
DL 2163 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 11 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 334 flights, with a median arrival 14 minutes early.
Set against the rest of the country, DL 2163's record is 11 points better than the US average of 77.6%. That gap is worth roughly 105 fewer late arrivals for every thousand flights.

These figures cover 334 flights between July 2025 and June 2026. The median arrival is 14 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 2163 flies
DL 2163 flies DTW to BDL without a single fixed slot. Its most common scheduled departure was 10:30, used on 75 of 334 flights, with 10:20 (60 flights) and 10:15 (38 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 10:30 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 2163 runs 4 points better at 88.1%. 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 2163 quarter by quarter
Quarter by quarter DL 2163 held fairly steady: 88.5% in Jul–Sep 2025, 84.6% in Oct–Dec 2025, 85.9% in Jan–Mar 2026 and 93.4% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 2163 did best on Wednesday at 95.7% on time and worst on Tuesday at 83.3%. Each day rests on about 48 flights, so a gap of 12 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 2163 runs late
One category carries most of the weight here. Carrier accounts for 60% of the 2,998 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.
- 60%Carrier
- 21%Late-arriving aircraft
- 12%National Airspace System
- 6%Extreme weather
The largest share of delay minutes, 60%, 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 1,804 of the 2,998 delay minutes reported here. The split is drawn from 2,998 delay minutes reported on DL 2163.
Cancellations sit at 1.80% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
7.0% 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 549 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.
DL 2163 is not only a DTW to BDL flight. It also flew BDL to DTW (334 flights, 86.9% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 334 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.
