These figures cover 344 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 latest arrival of the period was on 1 December 2025, 6 hours behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 1 December 2025 | 6 hours | Carrier |
| 14 August 2026 | 3 hours 17 minutes | Carrier |
| 9 December 2025 | 2 hours 44 minutes | Carrier |

Delay causes
Why DL 1429 runs late
Carrier accounts for 74% of the 3,440 delay minutes carriers reported here, and the remaining four split what is left.
- 74%Carrier
- 13%National Airspace System
- 11%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 74%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,549 of the 3,440 delay minutes reported here. The split is drawn from 3,440 delay minutes reported on DL 1429.
Cancellations are rare at 0.58%, 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
6.1% 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 about an hour, which a normal layover absorbs.
The 500 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.
The same number turns up on one other city pair in the data, including MCO to LGA (16), but none flew often enough under DL 1429 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DTW to CLT only.
One caution: this is a thin sample. 344 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 1429
