Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1523, check with Delta Air Lines.

DL 1523 earns an A−. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 17 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 50 minutes. That rests on 293 flights, with a median arrival 16 minutes early.

Set against the rest of the country, DL 1523's record is 17 points better than the US average of 77.6%. That gap is worth roughly 170 fewer late arrivals for every thousand flights.

These figures cover 293 flights between July 2025 and June 2026. The median arrival is 16 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When DL 1523 flies

DL 1523 flies MCO to LGA without a single fixed slot. Its most common scheduled departure was 07:05, used on 125 of 293 flights, with 07:00 (122 flights) and 07:20 (39 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 07:05 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 1523 runs 5 points better at 94.6%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 1523 next to MCO to LGA

Every carrier on MCO to LGA combined arrived on time 68.3% of the time across 5,262 flights, so DL 1523 is 26 points ahead of it. Delta flew 2,171 flights on the same city pair under all its flight numbers, including this one, and those ran 76.0% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 13 points.

Across the year

DL 1523 quarter by quarter

Quarter by quarter DL 1523 held fairly steady: 97.8% in Jul–Sep 2025, 92.2% in Oct–Dec 2025, 94.9% in Jan–Mar 2026 and 91.2% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights97.8%
Oct–Dec 202579 flights92.2%
Jan–Mar 202686 flights94.9%
Apr–Jun 202636 flights91.2%

Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1523 did best on Friday at 100.0% on time and worst on Sunday at 84.2%. Each day rests on about 42 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1523 runs late

One category carries most of the weight here. Carrier accounts for 55% of the 744 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.

Carrier
55%
National Airspace System
32%
Extreme weather
13%

Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.0 times the usual weather exposure. The split is drawn from 744 delay minutes reported on DL 1523.

Cancellations run at 4.10%, against 1.81% nationally. That is about one flight in 25 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

Badly late arrivals are rare here: only 1.1% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

The 950 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 two other city pairs in the data, including SDF to ATL (43) and ATL to SDF (43), but none flew often enough under DL 1523 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MCO to LGA only.

One caution: this is a thin sample. 293 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 1523

For a booking, the cancellation rate is the figure to plan around on DL 1523: 4.10% of its 293 scheduled flights did not operate. A late arrival costs about 50 minutes, but a cancellation costs the day, so leave a later option open.
