These figures cover 282 flights between September 2025 and August 2026. The median arrival is 11 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 7 December 2025, 1 hour 52 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The five worst days are spread across December, June, April and November, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 December 2025 | 1 hour 52 minutes | National Airspace System |
| 14 June 2026 | 1 hour 5 minutes | Late-arriving aircraft |

Delay causes
Why DL 1699 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 753 reported delay minutes.
- 38%Carrier
- 30%National Airspace System
- 26%Late-arriving aircraft
- 7%Security
The largest share of delay minutes, 38%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 288 of the 753 delay minutes reported here. The split is drawn from 753 delay minutes reported on DL 1699.
Cancellations are rare at 0.71%, 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
Badly late arrivals are rare here: only 1.1% 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 same number turns up on five other city pairs in the data, including RDU to ATL (244), IAH to DTW (36) and DTW to MCI (4), but none flew often enough under DL 1699 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to RDU only.
One caution: this is a thin sample. 282 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 1699
For a booking, DL 1699 has one of the better records a US domestic flight can show: 93.2% on time and 0.71% cancelled. That is a base rate, not a promise about any single day.
