DL 2928 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 347 flights, with a median arrival 2 minutes late.

The national on-time rate over the same period is 77.6%, so DL 2928 runs 6 points behind the country as a whole. Across a thousand flights that is about 61 extra late arrivals.

These figures cover 347 flights between July 2025 and June 2026. Beyond the headline rate, 10.7% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When DL 2928 flies

DL 2928 flies ATL to BWI without a single fixed slot. Its most common scheduled departure was 17:59, used on 39 of 347 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

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

A 17:59 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2928 runs 3 points better at 71.5%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

DL 2928 next to ATL to BWI

Across the year

DL 2928 quarter by quarter

DL 2928 did not run the same all year. Its best quarter was Oct–Dec 2025 at 78.5% on time and its weakest Jan–Mar 2026 at 64.2%, a swing of 14 points on roughly 87 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%

Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2928 did best on Thursday at 83.3% on time and worst on Sunday at 60.9%. Each day rests on about 50 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

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 6,378 reported delay minutes.

National Airspace System
40%
Carrier
39%
Late-arriving aircraft
17%
Extreme weather
4%

The largest share of delay minutes, 39%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,472 of the 6,378 delay minutes reported here. The split is drawn from 6,378 delay minutes reported on DL 2928.

Cancellations run at 2.59%, against 1.81% nationally. That is about one flight in 40 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.7% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The same number turns up on one other city pair in the data, including BWI to ATL (93), 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. 347 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: 2.59% of its 347 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
