These figures cover 272 flights between September 2025 and August 2026. The median arrival is 9 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.

Across the year
DL 1653 quarter by quarter

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 March 2026 | 5 hours 9 minutes | National Airspace System |
| 16 March 2026 | 4 hours 6 minutes | National Airspace System |

Delay causes
Why DL 1653 runs late
Carrier accounts for 50% of the 2,978 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Carrier
- 29%National Airspace System
- 19%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 50%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,492 of the 2,978 delay minutes reported here. The split is drawn from 2,978 delay minutes reported on DL 1653.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.8% 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 594 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 DTW to MCI (16), but none flew often enough under DL 1653 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DTW to ATL only.
One caution: this is a thin sample. 272 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 1653
For a booking, read DL 1653 as 82.4% on time with 0.00% cancelled over 272 flights. Those are rates from the past twelve months, not a forecast for any particular day.
