Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1576, check with Delta Air Lines.

DL 1576 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 7 points worse than the national rate of 77.6%. The late ones land an hour and a half behind schedule. That rests on 333 flights, with a median arrival 4 minutes early.

The national on-time rate over the same period is 77.6%, so DL 1576 runs 7 points behind the country as a whole. Across a thousand flights that is about 69 extra late arrivals.

These figures cover 333 flights between July 2025 and June 2026. Beyond the headline rate, 16.3% 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 1576 flies

DL 1576 flies MCO to ATL without a single fixed slot. Its most common scheduled departure was 15:15, used on 108 of 333 flights, with 15:35 (59 flights) and 15:31 (40 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 15:15 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 1576 runs level with that at 70.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 1576 quarter by quarter

DL 1576 did not run the same all year. Its best quarter was Apr–Jun 2026 at 77.6% on time and its weakest Jan–Mar 2026 at 65.6%, a swing of 12 points on roughly 83 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 1576 did best on Thursday at 83.3% on time and worst on Friday at 59.1%. Each day rests on about 48 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1576 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 9,476 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.

51%
Carrier
23%
National Airspace System

Extreme weather
9%

51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 9,476 reported delay minutes here, that single category outweighs weather by 6 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 9,476 delay minutes reported on DL 1576.

Cancellations are rare at 0.60%, below the national 1.81% 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 16.3% 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.

DL 1576 is not only a MCO to ATL flight. It also flew ATL to MCO (333 flights, 76.5% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 333 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 1576

For a booking, DL 1576 is a flight to put a long connection behind. 16.3% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
