DL 890 lands a B, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 360 flights, with a median arrival 9 minutes early.

These figures cover 360 flights between July 2025 and June 2026. Beyond the headline rate, 10.2% 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 890 flies

DL 890 flies RDU to MIA without a single fixed slot. Its most common scheduled departure was 08:08, used on 62 of 360 flights, with 08:05 (54 flights) and 08:20 (51 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 08:08 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 890 runs 4 points worse at 80.5%. 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 890 quarter by quarter

DL 890 did not run the same all year. Its best quarter was Oct–Dec 2025 at 87.5% on time and its weakest Jan–Mar 2026 at 74.7%, a swing of 13 points on roughly 90 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.

Jan–Mar 202689 flights74.7%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 890 ranged from 76.5% on Friday to 84.0% on Sunday. With about 51 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 890 runs late

One category carries most of the weight here. Carrier accounts for 76% of the 5,672 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Late-arriving aircraft
1%

The largest share of delay minutes, 76%, 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 4,322 of the 5,672 delay minutes reported here. The split is drawn from 5,672 delay minutes reported on DL 890.

Cancellations sit at 1.67% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

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. 10.2% 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 700 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.

Every one of the 360 flights under DL 890 in the data flew RDU to MIA. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 360 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.
