DL 1699 earns an A+. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 16 points better than the national rate of 77.6%.

These figures cover 281 flights between July 2025 and June 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.

Schedule

When DL 1699 flies

DL 1699 flies ATL to RDU without a single fixed slot. Its most common scheduled departure was 08:35, used on 50 of 281 flights, with 08:36 (31 flights) and 08:32 (29 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 08:35 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 1699 runs 9 points better at 93.2%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

DL 1699 quarter by quarter

Quarter by quarter DL 1699 held fairly steady: 95.6% in Jul–Sep 2025, 89.0% in Oct–Dec 2025, 91.7% in Jan–Mar 2026 and 94.9% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202591 flights95.6%
Oct–Dec 202573 flights89.0%

By weekday, DL 1699 ranged from 86.8% on Sunday to 97.6% on Wednesday. With about 40 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

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 864 reported delay minutes.

Carrier
33%
National Airspace System
26%
Late-arriving aircraft
22%
Extreme weather
14%
Security
6%

Extreme weather accounts for 14% 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 2.2 times the usual weather exposure. The split is drawn from 864 delay minutes reported on DL 1699.

Cancellations are rare at 0.71%, below the national 1.81% 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 1.4% land an hour or more behind schedule, against 8.1% 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 (243), 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. 281 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.
