Across the year
DL 2928 quarter by quarter
DL 2928 did not run the same all year. Its best quarter was Jul–Sep 2025 at 90.0% on time and its weakest Jul–Sep 2026 at 49.1%, a swing of 41 points on roughly 70 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.

- Oct–Dec 202580 flights78.5%
- Jan–Mar 202686 flights64.2%
- Apr–Jun 202691 flights73.9%

Scale runs 40% to 95%.
By weekday, DL 2928 did best on Thursday at 87.5% on time and worst on Monday at 60.0%. Each day rests on about 50 flights, so a gap of 28 points is worth noticing but could still narrow in another year.

Share of 335 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 74 departures that left 15 minutes late or more, only 6 made it up before arrival. In the other direction, 33 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 2928
The latest arrival of the period was on 16 March 2026, 7 hours 55 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 March 2026 | 7 hours 55 minutes | Carrier |
| 11 July 2026 | 6 hours 18 minutes | Late-arriving aircraft |
| 2 August 2026 | 5 hours 39 minutes | Carrier |
| 27 May 2026 | 3 hours 40 minutes | National Airspace System |
| 1 April 2026 | 3 hours 39 minutes | Carrier |
Delay causes
Why DL 2928 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 6,355 reported delay minutes.
- 40%Carrier
- 32%National Airspace System
- 22%Late-arriving aircraft
- 5%Extreme weather
The largest share of delay minutes, 40%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,573 of the 6,355 delay minutes reported here. The split is drawn from 6,355 delay minutes reported on DL 2928.
Cancellations run at 3.72%, against 1.89% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
10.1% 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 (60), but none flew often enough under DL 2928 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. 349 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 2928
For a booking, the cancellation rate is the figure to plan around on DL 2928: 3.72% of its 349 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
