Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1370, check with Delta Air Lines.

DL 1370 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 close to two hours behind schedule. That rests on 279 flights, with a median arrival 7 minutes early.

The national on-time rate over the same period is 77.6%, so DL 1370 runs 7 points behind the country as a whole. Across a thousand flights that is about 70 extra late arrivals.

These figures cover 279 flights between July 2025 and June 2026. Beyond the headline rate, 13.8% 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 1370 flies

DL 1370 flies MCO to RDU without a single fixed slot. Its most common scheduled departure was 21:24, used on 60 of 279 flights, with 20:59 (59 flights) and 17:15 (55 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 21:24 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 1370 runs level with that at 70.6%. 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 1370 next to MCO to RDU

Every carrier on MCO to RDU combined arrived on time 76.8% of the time across 2,702 flights, so DL 1370 is 6 points behind it. Delta flew 1,005 flights on the same city pair under all its flight numbers, including this one, and those ran 79.3% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight trails by 11 points.

Across the year

DL 1370 quarter by quarter

DL 1370 did not run the same all year. Its best quarter was Apr–Jun 2026 at 81.3% on time and its weakest Jul–Sep 2025 at 52.9%, a swing of 28 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.

Jul–Sep 202554 flights52.9%
Oct–Dec 202551 flights78.0%
Jan–Mar 202683 flights64.9%

Scale runs 45% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1370 did best on Wednesday at 83.3% on time and worst on Sunday at 54.8%. Each day rests on about 40 flights, so a gap of 29 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1370 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 62% of the 8,140 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.

Extreme weather
6%

62% 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 8,140 reported delay minutes here, that single category outweighs weather by 11 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 8,140 delay minutes reported on DL 1370.

Cancellations run at 2.87%, against 1.81% nationally. That is roughly one flight in 30 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. 13.8% 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 534 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 279 flights under DL 1370 in the data flew MCO to RDU. 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. 279 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 1370

For a booking, the cancellation rate is the figure to plan around on DL 1370: 2.87% of its 279 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
