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

DL 2025 earns an A+. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 16 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 349 flights, with a median arrival 10 minutes early.

Set against the rest of the country, DL 2025's record is 16 points better than the US average of 77.6%. That gap is worth roughly 161 fewer late arrivals for every thousand flights.

These figures cover 349 flights between July 2025 and June 2026. The median arrival is 10 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 2025 flies

DL 2025 flies MCO to SLC without a single fixed slot. Its most common scheduled departure was 07:00, used on 120 of 349 flights, with 07:10 (85 flights) and 07:20 (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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2025 runs 4 points better at 93.7%. 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 2025 next to MCO to SLC

Every carrier on MCO to SLC combined arrived on time 82.8% of the time across 1,530 flights, so DL 2025 is 11 points ahead of it. Delta flew 1,415 flights on the same city pair under all its flight numbers, including this one, and those ran 82.7% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 12 points.

Across the year

DL 2025 quarter by quarter

Quarter by quarter DL 2025 held fairly steady: 92.3% in Jul–Sep 2025, 93.8% in Oct–Dec 2025, 94.1% in Jan–Mar 2026 and 94.5% in Apr–Jun 2026. A spread of 2 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights92.3%
Oct–Dec 202580 flights93.8%
Jan–Mar 202686 flights94.1%
Apr–Jun 202691 flights94.5%

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

By weekday, DL 2025 ranged from 88.0% on Monday to 98.0% on Thursday. With about 50 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2025 runs late

One category carries most of the weight here. Carrier accounts for 61% of the 2,146 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
61%
Late-arriving aircraft
27%
National Airspace System
11%
Extreme weather
2%

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 1,306 of the 2,146 delay minutes reported here. The split is drawn from 2,146 delay minutes reported on DL 2025.

Cancellations are rare at 0.57%, 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

Badly late arrivals are rare here: only 2.0% 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.

At 1,931 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The same number turns up on one other city pair in the data, including EWR to ATL (16), but none flew often enough under DL 2025 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MCO to SLC only.

One caution: this is a thin sample. 349 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 2025

For a booking, DL 2025 has one of the better records a US domestic flight can show: 93.7% on time and 0.57% cancelled. That is a base rate, not a promise about any single day.
