Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2417, check with Delta Air Lines.
DL 2417 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 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 45 minutes. That rests on 268 flights, with a median arrival 10 minutes early.
Set against the rest of the country, DL 2417's record is 10 points better than the US average of 77.6%. That gap is worth roughly 103 fewer late arrivals for every thousand flights.

These figures cover 268 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 2417 flies
DL 2417 flies ATL to MDW without a single fixed slot. Its most common scheduled departure was 11:00, used on 127 of 268 flights, with 11:05 (100 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 11:00 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 2417 runs 9 points better at 87.9%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 2417 quarter by quarter
Quarter by quarter DL 2417 held fairly steady: 87.3% in Jul–Sep 2025, 91.0% in Oct–Dec 2025, 85.4% in Jan–Mar 2026 and 87.2% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 2417 ranged from 85.0% on Wednesday to 92.1% on Friday. With about 38 flights behind each day, a spread of 7 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why DL 2417 runs late
One category carries most of the weight here. Carrier accounts for 71% of the 1,351 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.
- 71%Carrier
- 22%Late-arriving aircraft
- 8%National Airspace System
The largest share of delay minutes, 71%, 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 953 of the 1,351 delay minutes reported here. The split is drawn from 1,351 delay minutes reported on DL 2417.
Cancellations run at 2.99%, against 1.81% nationally. That is roughly one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.5% 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 591 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 2417 is not only a ATL to MDW flight. It also flew MDW to ATL (267 flights, 87.5% 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. 268 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 2417
For a booking, the cancellation rate is the figure to plan around on DL 2417: 2.99% of its 268 scheduled flights did not operate. A late arrival costs roughly 45 minutes, but a cancellation costs the day, so leave a later option open.
