Across the year
DL 1267 quarter by quarter
DL 1267 did not run the same all year. Its best quarter was Jul–Sep 2025 at 80.0% on time and its weakest Jul–Sep 2026 at 55.0%, a swing of 25 points on roughly 66 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, DL 1267 did best on Wednesday at 80.9% on time and worst on Monday at 60.4%. Each day rests on about 47 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Share of 326 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 91 departures that left 15 minutes late or more, only 10 made it up before arrival. In the other direction, 18 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at BWI.
The worst days
Worst days for DL 1267
The latest arrival of the period was on 28 July 2026, 6 hours 56 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Three of the five worst days fell in July 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 July 2026 | 6 hours 56 minutes | Carrier |
| 19 July 2026 | 5 hours 13 minutes | Carrier |
| 9 July 2026 | 4 hours 25 minutes | Carrier |
| 30 October 2025 | 3 hours 52 minutes | Carrier |

Delay causes
Why DL 1267 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 6,970 reported delay minutes.
- 40%Carrier
- 30%National Airspace System
- 21%Late-arriving aircraft
- 9%Extreme weather
The largest share of delay minutes, 40%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,759 of the 6,970 delay minutes reported here. The split is drawn from 6,970 delay minutes reported on DL 1267.
Cancellations are rare at 0.61%, 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
11.3% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 577 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 BWI to ATL (236), but none flew often enough under DL 1267 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to BWI only.
One caution: this is a thin sample. 328 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
