DL 2276 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 5 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 358 flights, with a median arrival 2 minutes early.

The national on-time rate over the same period is 77.6%, so DL 2276 runs 5 points behind the country as a whole. Across a thousand flights that is about 50 extra late arrivals.

These figures cover 358 flights between July 2025 and June 2026. Beyond the headline rate, 9.1% 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 2276 flies

DL 2276 flies ATL to JAX without a single fixed slot. Its most common scheduled departure was 22:55, used on 67 of 358 flights, with 22:47 (56 flights) and 22:45 (56 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 22:55 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 2276 runs 2 points better at 72.6%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

DL 2276 quarter by quarter

DL 2276 did not run the same all year. Its best quarter was Apr–Jun 2026 at 77.9% on time and its weakest Jul–Sep 2025 at 64.0%, a swing of 14 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 202690 flights75.3%

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

By weekday, DL 2276 did best on Wednesday at 86.3% on time and worst on Thursday at 62.5%. Each day rests on about 51 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2276 runs late

One category carries most of the weight here. Carrier accounts for 61% of the 6,208 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

National Airspace System

Extreme weather
1%

The largest share of delay minutes, 61%, 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 3,790 of the 6,208 delay minutes reported here. The split is drawn from 6,208 delay minutes reported on DL 2276.

Cancellations sit at 1.96% 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. 9.1% 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.

Every one of the 358 flights under DL 2276 in the data flew ATL to JAX. 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. 358 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.
