These figures cover 277 flights between September 2025 and August 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.

The latest arrival of the period was on 3 July 2026, 3 hours 3 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. On four of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 3 July 2026 | 3 hours 3 minutes | National Airspace System |
| 26 July 2026 | 3 hours | Carrier |
| 18 March 2026 | 1 hour 48 minutes | Carrier |

Delay causes
Why DL 2417 runs late
Carrier accounts for 63% of the 1,855 delay minutes carriers reported here, and the remaining four split what is left.
- 63%Carrier
- 18%National Airspace System
- 17%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 63%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,175 of the 1,855 delay minutes reported here. The split is drawn from 1,855 delay minutes reported on DL 2417.
Cancellations run at 2.53%, against 1.89% nationally. That is about one flight in 40 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 4.5% 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 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.
DL 2417 is not only a ATL to MDW flight. It also flew MDW to ATL (276 flights, 84.5% 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. 277 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.
