These figures cover 354 flights between September 2025 and August 2026. The median arrival is 13 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 worst days
Worst days for DL 3110
The latest arrival of the period was on 18 May 2026, 10 hours 53 minutes behind schedule; most of its delay minutes were filed as extreme weather. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 18 May 2026 | 10 hours 53 minutes | Extreme weather |
| 14 March 2026 | 4 hours 45 minutes | Carrier |
| 19 August 2026 | 3 hours 46 minutes | Late-arriving aircraft |
| 23 October 2025 | 3 hours 13 minutes | Carrier |

Delay causes
Why DL 3110 runs late
Carrier accounts for 63% of the 3,947 delay minutes carriers reported here, and the remaining four split what is left.
- 63%Carrier
- 18%Extreme weather
- 14%National Airspace System
- 6%Late-arriving aircraft
Extreme weather accounts for 18% 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 2.9 times the usual weather exposure. The split is drawn from 3,947 delay minutes reported on DL 3110.
Cancellations are rare at 0.85%, 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
5.7% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last close to two hours, which a normal layover absorbs.
The 692 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 354 flights under DL 3110 in the data flew MCI to ATL. 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. 354 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 3110
For a booking, DL 3110 has one of the better records a US domestic flight can show: 88.9% on time and 0.85% cancelled. That is a base rate, not a promise about any single day.
